Accessibility information

If you have any comments about the information presented here, or have suggestions on how to improve it, feel free to contact us. So far, two pieces of information are presented here:

• An overview of the menu system in the game with more easily accessible textual information (for screenreaders) than is contained in the help that comes with the game.
• Information on the cast of characters with the same textual information as is available in the game (in graphical form).

Menu system

Main menu

• New player
  Click here to create a new player. Igor will ask you for a name in the statusbar near the bottom of the screen. Once created, the player will be selected automatically.
• Delete player
  Click here to delete the currently selected player. Igor will ask you if you are sure in the statusbar near the bottom of the screen. Once deleted, there is no way to undo it, so be careful!
• Player statistics
  Clicking here will take you to the statistics screen. It shows you a lot of information about the current player's progress. You can also see your progress in collecting puzzlepieces for the Time Machine here.
• (gap)
  At this point in the list, there is a small gap before the next option appears.
• Load other levels
  Clicking on this option will pop up a dialog asking you for another file with Igor levels (called a levelset). If you cancel you will be returned to your current levelset. Note that each levelset has its own player list so progress can be tracked for each levelset separately.
• Skip level
  Clicking on this option will skip the current level. Normally all levels should be played in order, since they will get more difficult. However, sometimes you are hopelessly stuck and then you can skip a level. Note that at most 3 levels can be skipped at any time. To skip another you have to solve one of the skipped levels first.
• Play level
  Click here to play the currently selected level. A valid player must be selected first. You can also replay levels you have already solved to see if you can improve your performance. The default shortcut key for this option is F10. If this key does not work, you can reconfigure it by using the 'Configure Igor' option.
• Load savegame
  Click here to load the prevously saved game for this player and levelset. Note that each player can have only one savegame, so you will not be asked for a filename. Saving a game can be done by simply pressing the 'S' key while playing. The default shortcut key for this option is F9. If this key does not work, you can reconfigure it by using the 'Configure Igor' option.
• (gap)
  At this point in the list, there is a small gap before the next option appears.
• Play recording
  Click here to play a recording of your choice. Igor will show a file dialog which allows you to choose which recording to play. You can make your own recordings by pressing 'R' while playing.
• Cast of characters
  Click here to find out more information about all the objects that are in the game to make your life miserable...
• (gap)
  At this point in the list, there is a small gap before the next option appears.
• Level editor
  Click here to start the level editor to make your own levels!
• Configure Igor
  Click here to configure the game. Options like sound volume, screen resolution, etc. can be set here.
• Credits
  Click here to find out who contributed to the game. These are the people you have to thank, or curse, for the game.
• (gap)
  At this point in the list, there is a small gap before the next option appears.
• Exit
  Click here to exit the game. Probably never happens, since you'll fall asleep exhausted while playing, and then continue again when you wake up.

• Status bar (near the bottom of the screen)
  This area shows important messages. Also, for certain questions you will have to type the answer here (for example, new player names).
• Block arrows (to the left of the player and level lists)
  These arrows allow you to scroll through the player and level lists. If you click on the arrow pointing right in the level list, it will start to play the currently selected level. To scroll through the level list more easily, you can use the PageUp and PageDown keys. If these do not work, you can reconfigure them by using the 'Configure Igor' option.
• Quick statistics (on the right half of the screen, just above the player list)
  This area shows a few of the most important statistics for the currently selected player. The first time is the time it took the player to finish all levels the first time, the second time is the total time played.

Configuration screen

• Configure keys
  This option allows you to reconfigure the (shortcut) keys used for most functions, so that they are where you find them convenient or logical. Once you click on the option, you will be asked to press (and release) a key for each of the following functions in turn. The default or recommended key is listed between parenthesis. Note that the 'pause' key that is present on most keyboards cannot be used for any function (there's a long and boring technical explanation for this).
  1. Left (Arrow left)
  2. Up (Arrow up)
  3. Right (Arrow right)
  4. Down (Arrow down)
  5. Escape/cancel (ESC)
  6. Action key (Space)
  7. Make recording (R)
  8. Pause game (P)
  9. Save game (S)
  10. Decrease visible size (-)
  11. Increase visible size (+)
  12. Default visible size (*)
  13. Decrease game speed ([)
  14. Increase game speed (])
  15. Default game speed (=)
  16. Left mouse button emulation (F2)
  17. Right mouse button emulation (F4)
  18. Middle mouse button emulation (F3)
  19. Speedbutton previous level (PgUp)
  20. Speedbutton next level (PgDn)
  21. Speedbutton load savegame (F9)
  22. Speedbutton start selected level (F10)
  Each time you press a key, the message will change in something saying 'Thanks, you can release the key again', and when you do that, the next key will be asked. Once you have configured all keys it will tell you 'all in-game keys configured'. From that point, you can configure other options or click on 'OK' to save the configuration and return to the main menu.
• Joystick
  This controls whether the joystick functionality is disabled (default) or enabled. If you do not use a joystick it's recommended to keep this disabled to avoid interference. Clicking on this option will toggle between disabled and enabled.
• Sound volume
  This setting controls the relative sound volume of the sound effects in the game. Clicking on this option will allow you to change it by entering a value from 0 (off) to 100 (maximum).
• CD-audio
  This opion is used to determine how you want your music played. The options are 'normal', 'shuffle' and 'off'. Igor uses your CD-ROM drive to play audio. You can insert any audio-CD of your choice and let Igor play it. Switch this option to 'off' if you don't want any music played, or you get short pauses in the game when Igor switches to a new track (this happens with some drives).
• Gamespeed (Hz)
  This setting determines how fast the game should be running. Normal speed is 50Hz, and valid values are 10 through 200. If you make this value lower, the game will run slower. This may be especially useful for those people who find it difficult to react to events and time certain manouvers properly on the default speed. Although it will make the game a little bit easier, the focus is really on thinking about how to solve a level, rather than 'blasting your way through' so lowering the speed will never be considered cheating. Of course if you want more of a challenge instead of less, you can also increase the speed. Note you can also change the speed of the game while you are playing by using the '[' and ']' keys (see 'Configure keys' option).
• Display hints
  This option controls when and how often to show the hidden 'hints' that are placed in some levels. Clicking this option will cycle between 'always', 'once' and 'never'. Note that some levels contain hints that are pretty useful, so the 'never' option isn't really recommended. Normally hints will be shown 'always', which means every time you activate the hint it will pop up. When you choose 'once', hints will only be shown once during each 'session'. So if you restart a level it will show the hints again, but if you are still playing the same level, you will not get bothered repeatedly.
• Screen resolution
  This setting determines the resolution that Igor runs at. Available options depend on your graphics card and monitor, but generally range from 640x480 to 1600x1200. By default, Igor will try to determine what resolution is best for your computer. If you change the option, the autodetection will be disabled and Igor will be forced to run at the selected resolution. If you choose a resolution that isn't supported by your graphics card or screen, it may cause a blank or distorted screen when you start the game. In this case, use the 'Safe mode Igor' icon in the start menu to restore proper settings (see the help-files included with the game for more details).
  Because modern graphics cards and monitors come in great varieties and have lots of configurable options, it's hard to predict what you will see exactly when changing the resolution. Please refer to the documentation for your graphics card and/or monitor for more information.
• Visible size
  This setting indicates the size of the screen that is used to display the level while you are playing. Normally this should be kept on 'largest' for best quality. Only with severe performance problems it may be useful to set this lower, although decreasing the screen resolution first, is recommended. Available options here are 'smallest', 'small', 'medium' and 'largest'.
• Fast navigation
  The game has some nice transitions between screens, and by default gives you a countdown of three seconds before starting a level. If you don't like this, you can set this option to skip the transitions, or skip most delays. Available options are 'normal', 'skip transitions', and 'skip most delays'.
• Automatic level exit
  This option controls whether the game will automatically return to the main menu after a level is finished (either by going through the exit or dying). By default it will do just that, but you can also set it to wait for the escape key. This allows you to see what else happens in the level. It may sometimes give you a clue for solving the level, or it can just be fun to watch the enemies running around, etc.
• Language
  This option controls which language is used to display the user-interface. Options depend on which version of Igor you are running, as not all languages were available originally. Clicking on the option will cycle between the supported languages. The setting will be activated after you click 'OK' to save the options.
• Sensitivity mouse in game
  This option controls how sensitive the mouse is for moving Igor in the game. By default this option is set to zero to disable mouse control of Igor in the game. It is mainly intended for people who have limited capabilities to use the keyboard or a joystick. A higher value means you have to move the mouse further before Igor will actually move. The value is measured in pixels, suggested value is 16 and maximum is 128.
• Lag mouse in game
  This option controls how slow the mouse responds for moving Igor in the game. By default this option is set to zero to disable mouse control of Igor in the game. It is mainly intended for people who have limited capabilities to use the keyboard or a joystick. A lower value means the mouse must be moved more quickly to make Igor move. The value is measured in frames, suggested value is 16 and maximum is 64.
• (gap)
  At this point in the list, there is a small gap before the next option appears.
• OK (save)
  Click here to save all options and return to the main menu. All changes will be activated immediately, except for changes to screen resolution (which requires restarting the game).
• Cancel
  Click here to discard any changes you made to the options and return to the main menu.

Cast of Characters

	This is Igor, the character the player controls. Your objective is to collect a number of Datapods, destroy all Guardians and connect enough Power sockets in each level. Only then Igor can leave through the Exit and extract the information in the Datapods to create a part of the Time Machine.
	Like Igor's control circuits, most of the interior of the alien artifact has mutated into Pudding. Igor can remove it by walking over it (he likes Pudding!), or by pressing the ACTION key and moving in a direction simultaneously. Pudding does not do anything by itself, other than be there and keep other objects from falling down.
	This object is called a Datapod. The design of the Time Machine has been mutated, divided and protected. The result is that it is split up into a large number of Datapods of information. On every level, you should collect a certain amount of them (see bottom right of the gamescreen), to be able to finish it and eventually build your very own Time Machine. You can pick them up by walking over them, or by pressing the ACTION key, and moving in a direction simultaneously.
	This object is called a Marble. Nobody knows how these Earthly things have ended up in the alien device, but here they are, and in great numbers unfortunately. Marbles will always fall downwards if they can. They can also roll off other objects. If Igor gets hit by one, it will crush him and he explodes. You can also push Marbles left or right, but only one at a time (i.e. there must be at least one empty space next to it on the other side).
	This is the Exit. Walk into it to finish a level. This only works if you have collected enough Datapods, have connected the required number of Power sockets and destroyed all Guardians on the level. The Exit can be destroyed, so be careful with it (though a level may have more than one Exit).
	When something in the game is destroyed, it will usually result in a big Explosion since the alien artefact is very unstable. Make sure you don't touch an explosion, or you'll catch fire too!
	This is a Pipe. If Igor enters it, he will come out at the other end. Of course he can only pass through if the destination end is not blocked. There are a lot of different Pipes. Some will only allow passage in one direction (which you can see by the arrow drawn on top), others in multiple directions. If a number is visible on the Pipe, it means Igor has to sacrifice that number of Datapods to crack its entrycode, every time he wants to pass through! There are also rumors that some Pipes are designed to twist the gravitational fields, so that passing through a Pipe may cause gravity to be turned on or off!
	Another example of a Pipe (see above). It's also a one-way Pipe, but this one has two separate entry and exit points. The colored arrows indicate how Igor can travel through.
	This is a Four way pipe. Igor can pass through both horizontally and vertically, provided the destination end is not blocked. Igor can't go around the corner in this Pipe, only straight through. If there is a number visible on the Pipe, it means Igor has to sacrifice that number of Datapods to crack its entrycode, every time he wants to pass through! There are also rumors that some Pipes are designed to twist the gravitational fields, so that passing through a Pipe may cause gravity to be turned on or off!
	This is a special Four way pipe, since it will always move Igor around the corner. Igor will always turn right inside this Pipe. If the destination end is blocked, Igor will not enter the pipe. There is also a Rotate pipe that goes the other way around. You can tell them apart by the direction of the arrow on it. If there is a number visible on the Pipe, it means Igor has to sacrifice that number of Datapods to crack its entrycode, every time he wants to pass through! There are also rumors that some Pipes are designed to twist the gravitational fields, so that passing through a Pipe may cause gravity to be turned on or off!
	Orange dynamite will explode when something falls on top of it, or when it falls itself. You can push it left or right, just like Marbles. There are also rumors of Orange dynamite that is filled with helium, and will fall upwards!
	Red dynamite can be picked up by Igor (just like Datapods), and then dropped somewhere else. Note the Red dynamite does not have a horizontal band over it like Orange dynamite. The absence of this band indicates you can pick it up.) To drop one, press, and hold the ACTION key for a while. As soon as the Red dynamite is dropped, you should run away, since it will explode shortly after you drop it. Of course you can only use Red dynamite if you have one or more with you.
	Yellow dynamite can be pushed around in all directions, and will never fall. The number on the dynamite corresponds with a number on a Terminal. All Yellow dynamite with a certain number will explode when you touch a Terminal with the same number, since a signal is transmitted from the Terminal to that Yellow dynamite instantaneously.
	This is a Terminal. When you press against it (try to move into it) it will send out a signal to all Yellow dynamite with the same number, causing the dynamite to explode. Make sure all bundles of Yellow dynamite are in the positions where you want them to explode before touching a Terminal.
	This is a Standard wall. There is no way to pass through it, or destroy it. Round objects (like Datapods) will not roll off.
	This functions exactly the same as a Standard wall, but is mostly used to show you that there is a helpfile (a hint) hidden inside. If you try to walk into it, you should see a textbox pop up. Keep in mind that these helpfiles can also be hidden at any other place in the level, and that a level can be designed to have Help walls without hints.
	This is another Wall. It can not be destroyed or moved. Round objects, like Datapods, will roll off if possible (if there is no object to it's side, and diagonally down). There are various Rounded walls that only have one or two round sides. It just means objects will only roll off in that/those direction(s).
	This is another Wall. It has the same functions as the Standard wall, only this one can be destroyed. If it's caught in an Explosion, it will be destroyed, leaving an empty space where you can pass through.
	This is one of your enemies. If you touch it, or it touches you (or a Copy of Igor), you explode. The only way to get rid of it is to let it explode (drop an object on top of it, or catch it in another Explosion). Razor CDs are not very clever, and always try to turn right and follow the Walls. Beware, there are rumours of a second type, which looks exactly the same, but always tries to turn left!
	This is also an enemy. It has the same behaviour as any Razor CD, but if a Mutated byte explodes, the information that is released causes up to nine (not eight? No, I told you it was mutated) Datapods to appear, which you can pick up when they've fully formed.
	This is a Door. You can only pass through if you have a Key of the same color (there are bronze, silver and gold Doors and Keys). If you have the correct Key, and try to walk into the Door, it will open up for you.
	This is a Key. You'll need it to be able to open Doors. Every color Key has it's own Door (bronze, silver and gold). You can have more than one Key of the same color in your posession at any time, so pick them up when you can.
	This is a Whirlpool. If you try to move onto it, you will be sucked down. The only way to pass safely over a Whirlpool is to wait until it's inactive. An inactive Whirlpool looks just like normal Pudding, and will activate after a short random period of time.
	These are Stairs. Only Igor can use them, and they'll keep Igor from falling down in a gravity environment. They can be destroyed by Explosions.
	A Floating marble is very much like a normal Marble, only because this one is lighter, it will only fall down when gravity is on. Igor can always push it horizontally, and if gravity is off also vertically.
	A Balloon will float upwards when possible. It contains hydrogen, so if it hits an explodable object (Igor, enemies, Orange dynamite, etc.) while moving it will explode. Balloons can also be pushed aside, like Marbles.
	Igor will only be allowed to travel through three tiles (maximum) of Water before he must breathe again. Stay under Water too long and Igor will rust, and explode. If an Explosion occurs, the Water will evaporate. Tissues will absorb Water too, and with Oxygen bottles Igor can stay under Water longer.
	Igor can push Tissues around, just like Orange dynamite. If a Tissue falls over Water, it absorbs all the Water, and will disappear with it.
	Oxygen bottles will allow Igor to stay under Water a while longer than normally. Igor can collect as many Oxygen bottles as he wants before using them. If Igor runs out of air before surfacing, he will rust and explode.
	Picking up a Hamburger gives Igor extra energy. For a short while, he will move at twice the normal speed. To see how much time is left, look at the status display at the bottom of the game-screen.
	This looks just like a Standard wall, but it's really a secret passage. If you look carefully, you'll see it's just a little darker than a real Wall. All objects in the game will treat this as a Standard wall, only Igor can pass through. If you are on a Hidden passage tile, other objects will see it's open, so you can still be killed by direct contact with falling objects or enemies (just like on any other tile).
	Expanding walls will try to extend themselves. There are two types: horizontal and vertical ones. After a short delay, the wall will see if it can expand. If nothing is blocking it's way it will expand. Expanding walls are indestructable, so make sure you don't need to be on the other side after it has expanded.
	This Elastic wall is made of a very elastic, but strong substance. It will continue to shrink, until nothing is left, unless it's being held back by an Elastic stopper.
	This is a Wall that can be destroyed by Explosions. The only other special effect it has, is that it will hold on to any Elastic walls attached to it, so they will not shrink.
	This is a Teleporter. It will teleport any moving object to another location. Its destination is always the same, and may be (but does not have to be!) indicated by a receiving Teleporter, or a Teleporter destination for a one-way Teleporter. Teleporters will not function when the destination is occupied. To get them to function again, the object on the Teleporter has to be moved off first.
	This is a Teleporter destination. It does not perform any function, but is sometimes used to indicate the destination of a one-way Teleporter. These destinations are optional and can also be present where no accompanying Teleporter is present.
	A Magic wall still contains the mutating power of the alien artefact. It will transform Marbles to Steel blocks, Steel blocks to Datapods, and Datapods to Marbles. It will only operate on objects that are directly above it. The objects will then fall 'through' the Magic wall if the tile underneath it is empty. While falling the object is converted. The Magic wall can be destroyed by Explosions.
	This nifty piece of equipment replicates Datapods, Marbles and Steel blocks. As soon as one of these lies on top of it, and either the left or the right side next to the Replicator is empty, it will read the object (swallow it) and spit it out to the free side. As soon as possible, it will also spit out a replicated copy of the object (to the left or right, depending on the first free side).
	This Lift will move up and down and can't be destroyed. If there is one object on top which can be moved, it will be pushed up (when the Lift moves up.) If the Lift goes down, the object may fall down again. Igor and enemies are not affected by the Lift.
	Really, this is what a Photon looks like in close-up. Well, at least the mutated Photons that happen to be in the alien artefact. Photons will always move straight ahead, unless they bounce off Mirrors. Photons do not harm you if THEY run into YOU, but only if YOU run into THEM!
	This Mirror will deflect Photons. If a Photon hits the Mirror, it will bounce off, as if it was a lightray hitting a Mirror (well, actually, it is).
	This Rotator mirror will deflect Photons, much like a Rotate pipe functions for Igor. The Photons that hit the Rotator mirror, will bounce off in another direction.
	This Direction mirror will deflect Photons in a specific direction (to where the arrow points).
	Exactly as the normal Mirror, but this one can't be pushed by Igor. Notice the yellow 'caps' on the ends of the mirror that hold it in place.
	The Diamond is such a valuable item, that whenever you find one (pick one up), all enemies are stunned for a little while. They will remain where they are, but they will still be dangerous, so avoid them, and make sure you're not near one when they start moving again.
	A Gift contains a Datapod inside. To get it out, drop something on it (for example a Datapod). The Gift will then explode to reveal the Datapod.
	A Steel block can be pushed, and will fall down if possible. It's square, so other objects will not roll off, and the Steel block itself will also not roll. It can be destroyed by Explosions.
	If Igor picks up Radioactive barrels, he will get sick. If he has picked up more than three he will explode due to the radiation, unless he has used some Medicine.
	If Igor has picked up any Radioactive barrels, he can use this Medicine to counter the effects. If he is not poisoned he will not use the Medicine, so don't worry about picking up too much of it.
	This type of Orange dynamite is very much like the normal Orange dynamite, but this one is filled with helium, and will 'fall' upwards instead of downwards.
	When you are on this object, you can save your progress (normally, you can use the 'S' key to save). Once it's used, it will disappear. If you are killed and you saved here, you can continue here later (by loading the game from the main menu).
	When you are on this object, you can save your progress, just like the Logfile (once). However, this one will remain available after it's used.
	If the level is dark, a Lightbulb will light up a 3x3 area of objects around it to help you find your way. Handle with care, because it can be destroyed.
	If Igor presses against a Light switch, the light for the entire level is switched on or off. The Lightbulbs are not affected. If you look at the object, you can see a small line to its left side. This line (red and/or green) determines the positions the switch can be in. Some switches can only be used to turn off the light, others only to turn in on, and still others to turn the light both off and on.
	The Conveyor belt moves all movable objects (except Igor and enemies) to the left or to the right if possible.
	The Exit which Igor must go through at the end of a level is powered by a special mutated energy. This power is generated by Power sources, but only when they are on a Power socket. On each level there is a set number (which can be zero) of Power sockets that must be connected to open the Exit.
	These Power sources must be placed in (on) Power sockets, in order for them to generate the power for the Exit to open. Be careful, because these Power sources can be destroyed, and if you lose too many there might not be enough left to cover all Power sockets needed!
	Igor can't move over tiles where this symbol is displayed. This can be very annoying, since other objects and enemies CAN move over it as if it wasn't there.
	How this entered the alien artefact, nobody knows, but it's the most powerful Superglue in the universe (really!) Once something gets caught in it, it stays in. Only Igor is strong enough to escape from it. He can also push other objects out of it.
	This is a Copy of Igor. You have to protect it at all cost. If one of these explodes, the real Igor will explode too. It will explode if something falls on top, an enemy touches it (if that enemy can also destroy Igor) or if an Explosion occurs in the same square. It can't be moved.
	If an object enters a Gray hole, it will be torn apart by the local gravity forces, and disappear with an Explosion. Nothing will be left afterwards (the Gray hole itself will collaps into itself too).
	Just like a Gray hole, objects entering it will be torn apart, resulting in an Explosion, but the Black hole will stay there to destroy more objects if they pass over it.
	CD presses are very dangerous. They generate new Razor CDs. After a set delay (can be different for every well), the CD press produces a new Razor CD to bother you. There is only one way to stop it: block it by placing an object (Datapod, Dynamite, even Igor) in front. When the object is removed the CD press will continue it's work where it left off. There are three different CD presses: one that generates left-turning CDs, one for right-turning ones, and one for random CDs.
	Once Igor picks up one of these, he will be forced to undergo a strict diet. He will not be able to pick up or eat other things (like Datapods and Pudding) for a short while. It can be helpful sometimes... Really...
	This Proximity mine will explode when any moving object comes within a 1-tile range (i.e. when it's moving next to the Proximity mine.) You can still 'eat' things that are next to a Proximity mine (with ACTION+direction), since they are not moving when you do that.
	Poisoned pudding looks like normal Pudding, only the green color indicates something is wrong with it. Igor will refuse to eat it, so the only way to get rid of Poisoned pudding is to let Poison dogs eat it (they are unaffected by it).
	Poison dogs are not very intelligent by themselves (the only thing more stupid than this is a Photon), but they are the only beings that are immune to the poisoning effects of Poisoned pudding. They will move left and right, and fall down if they can. If a Poison dog encounters Poisoned pudding, it will eat it away. Poisoned dogs will not kill Igor unless he tries to move into them.
	Eggs can be pushed left and right, and will fall down and roll off other objects if possible. They are very fragile objects, so when you try to push them when they can not be pushed, they will turn to dust. (And if you wondered whether the chicken or the Egg was first, here is your answer, or have you seen a chicken in the game?)
	Ghosts are evil creatures. They like the dark, and when it's dark they rest comfortably (don't move). But when the light is turned on, they are stressed, and get angry at Igor for turning the light on. In the light they can see Igor, and head straight for him. Their nature allows them to move over most things Igor can eat or move. Stay away from them, and try to keep the lights off!
	A Firefly is an extremely annoying enemy. This one also behaves like any regular Razor CD, so as usual, if you touch it, or it touches you, you will be killed. But if you try to kill this enemy, the heat of the resulting Explosion will be used by the Firefly to replicate itself. Instead of just one Firefly, there will be nine! The best way to deal with these, is to avoid them at all cost.
	A Flipflop circuit always moves straight ahead, until it can't move any further. It will then turn right (or left, depending on the type). Since the Flipflop circuit requires two clock cycles to operate, it will 'sleep' a while after every move it makes.
	A Shark is similar to the Razor CD, only this one will only move through water.
	A Marble golem is similar to the Razor CD, only when this enemy explodes, it changes into Marbles.
	This enemy creates Pudding tiles while it moves. You can use this to your advantage!
	Guardians are here to protect the data integrity of the alien artefact. They will prevent the theft of any Datapods, so Igor will have to eliminate them all before the Exit will open.
	This is just background decoration. In some situations it can mean something, but usually it doesn't. It has no effect on Igor, enemies or other objects (as opposed to Red tunnels.)
	When you are inside a square with a Red tunnel, you can't move across the red lines in this square in order to get out. However, nothing stops you from moving over red lines in neighboring squares. Be careful, since this means that sometimes you can move into a Red tunnel, but not out anymore! Other objects (and enemies) can freely pass through the Red tunnels as if they aren't there.
	Sticky floors make Igor move at only 1/2 speed. All other objects move at normal speed, so be careful that you are not being chased by an enemy when you move here, or that you have enough room to escape.
