The pixel art and sound effects go perfectly well together! This has a really cool spin mechanic and it feels really polished when executed. However, coming from someone that has completed similar games like Celeste, this is an extremely challenging platformer with how tight the safe spaces are. I think the the starting level designs could've been far less punishing while players are still getting used to the spin mechanic as well as the spin boost. I got stuck on the second level for quite some time before I finally realized how to get around it. I think when obtaining the spin boost, it should not be obtainable only after you complete a rotation while on it. There were a couple frustrating moments when I touched the spin boost upon jumping but it doesn't get collected unless you rotate on it. I think I would've preferred if the spin boost was just collected upon collision before or after rotating and it adding to a max allotted counter of spins. From there, a visual indicator like the player glowing, could mean that you can still rotate again while you're in the air. I did not continue shortly after the bouncy platforms were introduced. This was a very cool idea though and I can see how much work was put into it, great submission!
