Awesome thanks! Some very good points. The first level could definitely be easier. I think I took the difficulty for granted because I had gotten pretty good after playing a bazillion times :P
Also, yeah, they do heal, but it's such a small part of their overall health that you don't really see it. I was aware of it during the jam but wasn't really sure how to fix it, but I think I might have an idea of how I could make it clearer.
Thanks again for you thoughts and time!
