About Do Not Open
Do Not Open is a short, fast-paced first-person escape-room game with randomly changing puzzle combinations and survival-horror mechanics. You play as scientist Mike Goreng, trapped in a warped version of his own home and searching for his wife and daughter while an evil presence lurks in the darkness.
Judith’s Manor
The story takes place in the grand Victorian mansion of Mike’s aunt, Judith Goreng, who leaves the house to him after committing suicide. As Mike, you explore the mansion and uncover what happened there, including the guilt he feels over betraying his family. That guilt takes shape as a presence that tries to trap you, while a threat stalks the house.
Changing rooms and puzzles
Each time you pass through a door in the hall of Judith’s Manor, you enter a different layer of an area. Puzzle and riddle combinations change randomly, making each playthrough different from start to finish. You search the mansion for newspaper clippings, diary pages and other items; these clues reveal the story and make the plot a puzzle of its own.
You must solve the mystery before time runs out, or hide from the threat pursuing you.
