Thanks! I'm an animator, and my focus when designing is gameply, so it's nice that those are the things you noticed!
It actually never occurred to me to give heals after big fights...
The health parts restore you to full hp, if you can find them.
I'm making a 3d game and I'd like to use some existing textures,normal maps etc. Is that also forbiden?
I hope updating the game page (not uploading new files) after the jam is over won't cause any problems
