About DO NOT OPEN

WARNING: This video game may cause seizures in people with photosensitive epilepsy. Caution is advised.

DO NOT OPEN is a terrifying short and fast paced first-person escape-room experience, based on randomness in puzzle combinations, and classic survival-horror mechanics.




Mike Goreng is trapped in a warped version of his own home. What's going on? Where are his wife and daughter? As a scientist, Mike can't come up with an explanation for what is happening, but his instinct tells him that he is in severe danger... and something evil lurks in the darkness.
Being in Mike's shoes, you will experience tense moments where your heart rate will accelerate. Meanwhile, the personification of guilt, which Mike feels for betraying his family, will try to trap you.
Will you be able to run away from it?





The story of DO NOT OPEN takes place in the grand Victorian mansion of Mike's aunt Judith Goreng who, after committing suicide, leaves the house to her nephew.

Remember to explore every corner of the mansion and discover all its details.





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 combinations will change randomly so that each game is different from start to finish.



To unravel the terrible mystery of the manor, the player will find different newspaper clippings, diary pages or other items in each game, making the plot a puzzle in itself. But he must do it before time runs out, or he'd better hide from the terrible threat that stalks him.

Are you ready for the DO NOT OPEN challenge? HIDE, SOLVE or DIE!

A thrilling escape-room horror game in an unsettling Victorian mansion. You progressively complete atmospheric puzzles with some time pressure, uncovering layer upon layer of dark secrets room by room. It isn’t full of cheap blooms your audience will expect from a horror game, it is more of an unsettling dread, leaving fans of immersive horror and mystery in bliss.
