DO NOT OPEN is a challenging survival-horror classic with gameplay based on escape-room mechanics. Each time the player crosses a door of the Hall of the Victorian mansion Judith's Manor, he will enter a different layer of each area, and its puzzles and riddles will change randomly so that each game is different from start to finish.
