The Backrooms Game is particularly powerful because it uses liminal space, which are places that feel like they are between places in real life, such empty offices, parking lots, or hotel halls. The gamer feels uneasy in these places because they seem familiar but inappropriate. The Backrooms make this sense even stronger, so that even an empty hallway feels hazardous. It's a different kind of scary: not from monsters or blood, but from the idea that you're really alone, lost in an endless space.
