Fun Vampire Survivors-esque game! Loved the music and the art, and the upgrades were fun though sometimes didn't feels too impactful overall.
Biggest gripe would be the lag, I know that a bunch of enemies on screen means a lot of things to render and check but that's the biggest programming issue to solve with these types of games, so I hope that you work on this further and figure out how to optimise that more. Outside of that add a volume slider please.
Really fun game though, hope y'all keep working on it post-jam!
