The idea was very cool, but I miss to have more puzzles/situations like the first desk that it blocks the pass. As other people say, the gaurds are very easy to trick them and spamming the space bar, you can reach any button without need to move anything or try to "solve" the situation.
I cannot continue playing because I was locked in a room that is locked and spawn two guards when you press the button. After that I cannot go out of that room anymore...
Fun fact: I spamming the button of the room and rewind the time, and infinite guards were spawning until the game cannot process to many instances :)
