I think you have a pretty cool game so far, but as it is right now I had to quit because I stopped enjoying the game at the first boss. His moves are all over ten times faster than yours and you have to anticipate them because you can't possibly react to them. Especially because you can't attack while jumping or moving. I'll add to the movement too slow/controls too clunky category - if you update the controls to act more smoothly and allow attacking while moving, I'll try the game again.
