Book of Demons

Book of Demons is a single-player action role-playing game with deck-building mechanics. The story is set in the troubled Paperverse, where a once-peaceful town is overshadowed by a cathedral harboring evil in its catacombs. Players take the role of a hero returning after years away, only to find the land corrupted by monsters and ruled by a demon deep within the dungeon. The hero must descend into the labyrinth, confront the corrupted forces within, and restore balance to the town.

The core gameplay is built around simplified dungeon crawling combined with card-based abilities. Players move along predetermined dungeon paths, exploring rooms, fighting monsters, and looting treasures. Combat is real-time but governed by cards that represent weapons, armor, spells, and consumables. Cards replace traditional inventory, with the player managing a limited number of active slots and balancing resources like mana and charges. Defeating enemies and exploring dungeons rewards new cards, upgrades, and gold for further customization.
