Hi!
I liked you game. The controls felt pretty smooth and you definitely had some nice Metroidvania elements in there. I really liked the way your healt system worked. Being able to build yourself a huge buffer by collecting more and more health felt really good. I would have wished for a little bit more enemy variety though.
The only other issues I had, that I couldn't see my characters feet most of the time and that the game closes after you lose :D
