Very nice Vampire Survivor-like game. I like that you put a good number of different upgrades, so there's a lot of different build possibilities. For a bit of feedback, I would have liked a way to check my current upgrades. Maybe a pause menu or an icon I can hover while the upgrade screen is up.
I do have to give a shoutout to making it so the enemies don't all bunch on top of each other when following the player.
