Ooh im really diggin that minimalistic art style, brought me back in times of Magic Survival, when vampirelikes werent even a thing x)
Game lacks in waves and enemy variety, and more importantly proggresion or upgrades. Also some sfx and music could elevate the expirience for sure.
Nonetheless art style alone made me play it and lock in haha. I'll defenetly try to beat it >:)
