Cute game! The idea of the enemies sending you in the air and falling into the next level is very neat, I like it! the art and look of the game is really nice, but I do think the boxing gloves feel out of place with the rest of the style.
Like some other players mentioned, they can be hard to avoid, especially when spawning in a level, where you get somewhat spawncamped sometimes.
There was also some visual bugs, but the main buzzkill for me was the controls. I don't think you should move up and right when pressing w, it feels counterintuitive.
Did you use a procedural generation algorithm, or did you handcraft the different levels? That was cool! Congrats on submitting to the game jam!
