I really like this game, there's something so satisfying about hitting the boss, switching direction, and hitting them again in a loop. The only criticism I have is that it's unclear when I get hit. I don't know if it was removed or there's some kind of glitch, but there are no healthbars. I remember playing this a while back and there were, so I'm not sure what happened with that.
Overall, a really cool game, good job!
(Also if you have a free moment, I would really like it if you could give me some tips on my game, I'm planning on remastering it and possibly selling it on Steam, so any input would be greatly appreciated)
