Really delightful graphics and animations! Love the backgrounds, and also the sounds. It feels pretty nice to play too. My only critiques would be to maybe have some instructions in the game itself for buttons/what you're doing, and have a bit more feedback to taking damage (maybe a sound or extra animation). Also some of the platforms feel VERY close together, I think it would be nice to set em further apart, because jumping with that animation is just very pleasing. Great job!
