Brutal topdown slasher. Expect to die a lot, and quickly.
You have only one move - whirl around like a maniac and woe betide any fool that gets in your way.
Delve into dungeons like the Cursed Crypt of Neverending Tragedies and retrieve valuable artifacts like the Forbidden Grimoire of Inscrutable Vampire Mating Rituals. For example.
Collect spells and perks to upgrade your character with enhanced abilities. Then die anyway, because it's dangerous out there.
