Book of Demons is a Hack & Slash in which YOU decide the length of quests. Wield magic cards instead of weapons and slay the armies of darkness in the dungeons below the Old Cathedral. Save the terror-stricken Paperverse from the clutches of the Archdemon himself!

Official stores and keyshopsOfficial stores sell the key on behalf of the publisher (Steam, GOG, Humble…). Keyshops are third-party key resellers (Kinguin, Eneba, Instant Gaming…): they cost less but aren't the publisher's store, and support and refunds go through them. Check the key's platform and region and prefer sellers with many reviews. On Linux what matters is that it's a Steam key: the game starts with Proton just like one bought on Steam.
