I feel like this wasn't made with this game jam's themes in mind at all. But aside from that:
Enemies do not collide with world or fall. No damage sound means I don't know when I've been hit. I cleared the map, but doesn't seem like there was an end screen (or if there was, it never triggered).
Edit: I didn't know there was a stun mechanic. Using the sword kills anything with 1 hit.
