Pretty nice! Though I'm not quite sure how the enemy health works - it seems like either some hits do no damage, or it takes more than one hit for the enemy's health bar to change.
Since Santa is Yellow, he is only hurt when the Notes are Red (post-bounce). I probably should've had a little illustration pop up upon the game loading. Thank you for the feedback and thanks for playing!
I see, so a better Boss Health UI would probably be a Megaman esk one so every time the boss is damaged, his health will properly communicate a loss of hp. Alrighty I get it now sorry lol.
Yeah, I think it would be more intuitive for the player to avoid confusion. It can still be snowflakes, as long as there's visible change for every successful hit.
