The scenery and atmosphere are all super lovely, it makes it feel very polished. And that cover art is just amazing! The music is beautiful, and the movements are super crisp, it's really satisfying to jump around the space. The camera panning between scenes can be a bit difficult during the platforming, it's hard to keep my momentum when the camera is moving while I'm trying to make platforms. The Z key being the spin is very difficult to hit right after jumps, I think remapping that button would make the game feel a lot smoother to play. The explanations at the start are really helpful, I love the way each interaction is broken down, and I wish those would have stayed up to the bucket and cloud section, since I was definitely feeling a bit lost there. Overall I think it just needs a bit more playtesting and polishing on the level design -- there's some really satisfying pieces here, you just need to make some tweaks so the game has better flow (the bucket could be at a farther jump distance, so you didn't have to awkwardly back up to try and make such a narrow platform). I like the challenges, I think they're exciting to get right, you just need to ease the player into it a bit more before introducing spikes, buckets, and clouds all at once without a checkpoint in between them.
