Yes, having fun and learning from our mistakes is all part of the jam experience.
The Health system wasn't obvious, maybe have your missing health start flashing when you aren't attacking and then faster as its closer to healing. I can see the idea of the system, only with the way enemies work so far, you can just hide on one side of the map.
The part about having a game breaking bug slip through always hurts.
I look forward to seeing where you can take the game as you improve it.
