Love the artstyle, also the little quirks like the sticks holding the characters up or the runes in their speech bubbles! It's a bit difficult to pick up as I couldn't understand what to do in the first horizontal phase, I had to look at your comment; I love however the idea of the 2 phases with each boss, the first one kind of raking in health and the second one defending it. The UI might have to be revised esp for the second phase: the > was hidden under the health bar so i couldn't see it at all, also it's a bit too difficult to keep track of both sides of the screen, even though the game isn't particularly punishing when missing a note. Would also love a different song for each boss!
