Wonderful idea, it fits well on the theme! I loved it! It's really great, very original. The only thing I didn't like is that the rewind is kinda of hard to get used to it, it rewinds first our last moves and then makes the game harder. Maybe you could rewind in the order that you did the moves. The jumping sometimes is too fast, you are pressing jump button and when you fall you jump again already(add a short cooldown between jumps)
Anyway, is a REALLY cool game, you should be at the top of the page!
Hey, check it out my game too, it's actually pretty similar to yours!
