Loved the atmosphere of this game, the art and audio were both fantastic! It's also nice to see a point-and-click in a jam game. One small detail that made a huge difference was the names on the wall of the cell, it added a lot of character and I always stopped to read the name of the person I had just gotten killed. I managed to beat the game with 11 deaths!
My only nitpick would be what others have already said, it would have been great if there were even more persistent elements since you do end up going through the loop so many times. The button that opens the first door would have been a great one to keep permanent! Overall though, this was one of my favorites so far, fantastic job!
