This idea is really cool, and I want to play it more, but I had some trouble with glitches. After dying, trying again starts you with no health, so you get one-shot unless you restart the whole game. At one point I managed to glitch where I seemed to be flying, and the boss was just gone, and for the second boss I just disappeared. The story, music, art and concept are all amazing, it just needs a bit more polish for me.
