This is really neat, the art style is great and I like how varied the levels are and they all look fun and have fitting music - As I played I kept looking forwards to seeing what the next level was like, well done :) The rewind mechanic to go backwards is cool too and the movement feels pretty solid
The one small thing that caught me was that I accidentally pressed the skip level key when I was meaning to restart the level. Maybe the skip key should not be so close to other keys you'd normally press during gameplay?
Either way a nice fun game :)
