I really like this, the music is fantastic, the art and theme is very good, and I love the little backstory. I have to agree with others though, that I had to get used to the hitbox, because it is quite hard to see when I will hit and when I won't, and I am quite vulnerable even when I learnt the enemy's attacks. I think with adding some more enemies, adding some movement to the player and give some visual cue to the hitbox, this can be a grate base of a longer game I would gladly play with :D
