Since there's not much here - i will comment on the controls. the jump feels far too stiff, with the height being and and the speed being incredibly fast - as compared to the running, which is simultaneously slippery and stiff, having instant turns but slipping when you stop pressing anything, and it is slow. Slip-sliding around seems like something an axolotl would do, so i suggest maybe lowering the jump speed so that your jumps feel more natural and making it so turning isn't so instant.
