I love the art and the music! There's so much of it and of really good quality, it's impressive how much you managed to do in such a short amount of time. My impression is that visual cues are harder than audio cues when it comes to rhythmic things, I think if the jump was synced with the music, or given an anticipatory beat, it might have felt more natural to play. I really liked the level design, it was on the harder side for me since the first world (I reached until around halfway through the third world), but all the mechanics kept each new world fresh, and all levels were exciting. Great work!
