Tormentum is a dark point ‘n’ click adventure game wherein a nameless hero with amnesia finds himself in a place between fantasy and nightmare. Wandering through strange lands, he struggles to discover the truth about the world around him, as well as about himself.

The dreamlike, nightmarish atmosphere of the game was inspired by the works of painters H.R. Giger and Zdzisław Beksiński. The game's final look and feel was also strongly influenced by the universes of games such as Demon's Souls and Dark Seed.

It features three realms, 75 hand-painted stages, and 24 logic puzzles.
