It's a great game for this jam! I was really feeling like developing my game, adding gameplay elements and just having fun. It progressively gets difficult, which is good. You could add an upgrade to indicate damage (because it's unclear when I get hit or when I hit enemy), and definitely health for a player.
Also be sure to rate my game too https://itch.io/jam/blackthornprod-game-jam-1/rate/319192
