Didn't really see how it fits with the Rewind, must have missed the controls on that, but I did enjoy the colors and simple art. Nice work with that, you can fix the player getting stuck on bricks, by either using capsule collider for player, or one whole box collider for platform, or composite collider + tile collider if you are using tiles. For the Jump you can also use bigger jump force, and bigger gravity. That way the jump will snapier and feel better ;) Nice work! ;)
