Book of Demons

Book of Demons takes place in Paperverse, a world that exists entirely inside a pop-up book. It’s a tale of good and evil about saving the world from the ultimate devilry. Inspired by the dark and gloomy atmosphere of the first Diablo game, Book of Demons is part tribute part parody of hack & slash classics.
