So cute! The controls feel great, and I love the jump animation haha.
It took me a while to understand how the rewind worked, I guess I'm biased after playing so many games with the more conventional mechanic... It's nice to know that jump isn't necessarily going to be the last one. Makes me wish life had such a feature :P
A minor suggestion: it would be better if you didn't have to wait for the bar to clear before rewinding. I also at least once fell from a platform when I swear was standing on it...
Good job!
