At this point I've watched this a couple times, admired the characters and saw how broken some of the gameplay is, but I'm late to the party on actually playing and reviewing the game. Fortunately, plenty of other comments have hit the main things (insane grind, no checkpoints [understandable for a jam]) and I know you've already fixed the "enemy attacks dead people bug"
I think the best thing about this game is that it breathes life into a 'VN-character' archetype (despite it not being a VN). You have kind of demoed a system that allows you to learn about and connect to a character outside of massive walls of text. I think if you wanted (and on possibly a different project), you could strike a really amazing balance between VN story elements and this combat/characterization system.
Congrats on the release.
