Great concept! I'd like to see more about this game :) The character is amazing. The animation and particles of the rewind mechanics are great. Also good music. The graphics are the part I liked the most. But there are some things to improve. The game is a little bugged. At the end of the second level I don't understand why many times the game didn't allow me to go to the next level when I reached the top-right platform. But with such a short amount of time it is understandable, and I suppose you are just 1 programmer and 1 artist. Moreover, the level design could be improved by making more evident the part of the level you can interact with and also make clear where the end of the level is. In the end, well done ;)
