Love this interpretation of the theme! The sprites are simple and cute, and the music is nice.
I think it could've felt more final-boss-y? Having multiple phases helped but maybe it could've had some over-the-top name instead of just "Vampire" to make it feel less like a random encounter.
Even though I suck at the game (and the timer felt very unforgiving to me), the level mechanic kept me going, since I knew I'd eventually get better as long as I kept throwing myself at it, so that was a good call! I do think we could've gained more xp/leveled up a littleee faster.
Fun game!
