So... two months later and I finally know about the missing tile. Now Atlases can proceed to the third room too YAY

Forgot the thumbnail, again
Also the original thumbnail is lost *cries*
I spent so much time on it *cries more*

Added a reset button to the difficult room, cause people did an unintended solution to get the ball down by respawning cube at the right time, and getting it stuck at the top.
Added doors between singleplayer rooms, cause cubes could be lost easily.

Forgot the thumbnail

Changed the sequence of the rooms, to make the learning curve less steep.
Moved the difficult room to the end - since it is a showcase level primarily and the showcase part was after a pretty difficult part.
Glass panel room is now unescapable, once you enter it - to force the solution.
Removed the laser from co-op piston-platform-room. Now people are more likely to notice the piston platform itself and not be like "idk how i did it, and i don't care lel wubwubwubwubwub".
Added a shortcut to the co-op chambers, cause i care.
^lel
Exit room is now encorporating the funnel from the difficult room.
Exit door is now blue.
Added some lights.
Something something.
Comment "I have read and agree to the terms of use" if you read this.

Changed the last singleplayer room - no more faithplate and timed button - cause people are bad at Portal 2.
Moved the laser field in the first cooperative room further, cause people are bad at Portal 2.

Changed the second two-player room, to remove the death from equation
