I did manage to softlock at the checkpoint after the stomp ability by going there without the stomp ability. But otherwise pretty fun in the later 1/3rd especially. Good use of basic shapes to make some interesting enemy and environment visuals and great use of the palette too, though I think the level geometry itself could've used some more visual variety for sure.
The animations were a highlight for me, the platforming was pretty good with only a few nitpicks being it wasn't very clear when the hover was working vs out of juice, and I think the stomp into jump could've used some more audio-visual feedback to help distinguish it from a late jump after a stomp which is just a regular jump at that point. More work in general on the sfx would've gone a long way actually, but it's good that there is already a lot here.
Also the cat looks like a fish in the 2.5D mode
