Nice game! Is a good idea, and I like the implementation of the art and the lights, but the movement is a kind of weird, you feel the jump not that responsive and the speed of the movement is too fast considering the speed of the jump and the falling time, and that makes the game hard, I also think that I can move while rewinding, but not at control. Maybe a bit more of control about how you move or how you can a recover after you get rewinded.
But over all great work!
