My main complaint is that it isn't very clear that the game doesn't want you just throwing yourself over to the other side of the room until you purposefully and accidentaly throw yourself away too many times going through doors while looking for the solution.

Otherwise, I enjoyed the game and the puzzles! It actually game me a bit of motion sickness, but I'm kinda bad about motion sickness in first person games, anyway - I powered through it because I liked it enough xD
