Good work on the retro aesthetic!
I felt the difficulty could have ramped up much faster, I was just jumping wall to wall to get the spawning enemies at first.
I also recommend renaming History to just Story, so it doesn't seem like a button to click to read lore.
Sorry if this was intended, butit felt a bit "floaty" to me, like the objects didn't feel like they were solid or had any impact when interacting with the player or projectiles.
I'm not big on the vampire survivors formula, but it looked like you put alot of thought into the upgrade system, so nice job!
