Cool one! These makes my brain hurt, but the amount of satisfaction when you resolve the room is just great. There is one thing I would suggest into the future. Sometimes the room was not easy to read in terms of colors. For example I was really missing some sort of shades that would help the perspective and the orientation as you are setting some sort of a shade to the player. Maybe even a simple outline for the player would also help, but in general just to be carefull when deciding on the colors and how they will fit in the overall view. It is just a suggestion, not really a complaint ;) I enjoyed your game a lot!
