Very clean and polished game. I really enjoyed it. It's an interesting way to make you think about your rewinding.
2 Small comments: The wording on one of your signs: "You're invincible until you get rewinded" made me think that my character is invincible, and dies when the rewind touches any traps. Possibly think of rewording there. And then possibly add a button to end your rewind early. A lot of times I sat waiting for 2 seconds because I already had the coin and was waiting for the timer to end.
Apart from that, REALLY fun game!
