Nice going!
Original use of the limitation and a very trippy adventure. A nice sound track would have definately made a difference. You should consider adding one after the voting.
Is the game a comentary on work/office and confinement? Seems their was something symbolic going on. :)
In terms of gameplay: thanks for the well calibrated checkpoint system. Without it, the game would have been too hard! (Still a bit hard, I would argue. Didn't make it to the end.)
Cheers,
