The concept is very nice, and the puzzles look interesting.
It's a bit annoying that hitting the "wrong" tiles kills you. It becomes a "wire loop game" rather than a puzzle.
Seems like this game was inspired by Pixar's Lift.
What makes this game great, in my opinion, is that the frustration of getting the wrong keys is translated in amusement when the sleeping man's body hits the walls, ceiling and furniture.
I played the game a few time, and was laughing from start to end.
