A place can be totally deserted and still give you the feeling that you are being watched. That's the same feeling when you wake up in Terror in Backrooms Valley.
Your nightmare may start in the infamous, endless yellow hallways, but the adventure soon spreads into the unknown. Terror in Backrooms Valley is continually changing the environment to keep you on your toes. Soon you’ll be roaming haunted abandoned motels, submerged tunnels, disused research labs, and a truly disturbing valley. Every new place is a piece of the puzzle, carrying pieces of a far broader, far darker story.

Leave your sharp reflexes behind. There's no furious chase scene here; the stress comes in the disturbing atmosphere and the weight of the choices you make. The wholly mouse-driven action means that it is incredibly easy to pick up, letting you focus exclusively on the mystery:
What’s brilliant about the game is how it makes you doubt yourself. A conversation that is perfectly regular could have a tiny hint somewhere, and basic decisions might feel a little “off.” Other survivors you encounter are unpredictable and hard to read. They won’t answer questions; they change the subject on purpose; they say things that are just not true. You have to read between the lines and make up the reality for yourself.
All you can think of at first is how you can escape. But then, there are signs of your character's past in the valley, and the goal changes. A strange artefact found in a dusty research room can completely recontextualise a discussion you had early on in Terror in Backrooms Valley. Suddenly, you are not trying to discover the escape, but the truth. It’s a slow-burn mystery that leaves enough questions unsolved to keep your mind running long after you’ve stopped playing.
