I can see it being a good game for speedrunning, however I took it rather slow (and was rightfully called out for it at the end😅). The levels mix and match different mechanics nicely, with the upside down sections for added challenge. I appreciated how the colliders for spikes are a bit smaller than their sprites. The main thing that could be improved is the feel/visual feedback of walljumping, maybe with a separate "sliding down" state.
