God damn this game jam submission is actually incredible!! I loved the gameplay so much I could genuinely see a game being made out of this. One recomendation I'll give is to use more smear frames in animating the attacks; currently, the attacks feel a little slow, and that's ok if that's what you were going for, but if you cut some of those animations and replaced them with smears, they could look way smoother and responsive (that's what I did for my game, if you wan to check that out it's on the last minigame lol). Here's a video that also helped me get the smears right:
Good luck with the jam guys!
