Book of Demons – a charming and inventive hack & slash that blends classic dungeon crawling with card‑based mechanics and a playful paper‑cutout aesthetic. You step into the pop‑up world of the Paperverse, where every item, spell, and skill is represented by a card. Instead of endless clicking, you build and adapt your deck on the fly, choosing the right mix of attacks, defenses, and special abilities to tackle procedurally generated dungeons beneath the Old Cathedral.
