Pretty neat mechanic! It seemed like the enemy health was a bit more fine-grained than what was displayed, or maybe I was misinterpreting what was being counted as a hit. It might help clarify to have a visual indication whenever damage is done. The floor seemed icy, which is apt for this time of year (at least in the northern hemisphere), though it sounds like from a reply below that it wasn't intentional. It might be that you're applying a force in the direction of the arrow keys, instead of setting the velocity in the direction of the arrow keys, though I don't know what your setup is like, so I can only really guess. I think it's okay icy, though, 'cause it adds a bit of challenge. Congrats on completing a game for the jam! :)
