Nice job! I like the graphics and concept! The player movement feels good and I like how the rewind mechanics are all on the mouse! I also like how there's a rewind bar, so you have to be careful with how you rewind objects.
One thing is that I think the music loop could be a bit longer and a bit more interesting since it had the same tune repeating the entire time (That might just be me though).
Other than that, great work!
