The key bindings are a bit weird. it took me quite some time to figure out that it was z to confirm in the menu instead of enter or space. You could mention it on your itch page.
The games feels very polished, its goregous and the sound design is really good. Is the game in a fixed amount of rounds ? I was under the impression that I sill had lives left when the score screen displayed.
Other than that I can't think of anything else to say, congrats !
