Ok. Feedback time!
I really dug the music. Great job with that! The controls were also great! They really fit the game well.
The only bad thing I can say about the game is that I don't know how I won each level. I would always go to the end, grab the coin thing (not sure what it was), and then wait. After a bit, I was loaded into the next level. I assume, the version of me that is supposed to die died, but I'm not sure how. It seemed like the other version of me walked further than I walked in some cases and that killed it. I'm not sure.
Despite that, your game was really cool! Amazing job with it! (:
