Decent base for a game. I think the controls and game loop could use some more iterative polish. I think this would have benefited from more actions you could perform (lunge, spin, ultimate, etc). In terms of survivor games (action/arena; vampire survivor-like), I think this just needs more meat.
However, this jam was specifically narrow to focus on learning and getting something done that aligns with a theme. This certainly does that! Great job!
