An ancient Beast stalks the caverns of the Red Dungeon, and it has chosen you as its prey. Summon all of your courage and make your escape in a nail-biting endless runner/platformer. Steal the souls of all those who stand in your way to bargain with the Soothsayer for a tale of the dungeon’s horrors. But remember the one truth of the Dungeon: there is no way out.
