I loved the simplicity in the combat but the complexity in the stats and data. I encountered a bug where the enemy isn't doing any damage to me and he's just increasing health (currently at 1200 HP as I'm writing this) and I can't exit combat so this is interesting. The art style feels a little inconsistent between the player, background, enemies, and font but I think it works fine for the game jam. I wish the heads up display was a little bit easier to read since there's a lot going on with the stats all thrown in there.
Other than that I like the concept here and with a few tweaks I could see this as a pretty amazing game.
