In a fierce tug-of-war between the sanity of a professional observer and the most primitive instincts, the main character is pushed into a more grim setting: the anomalous space of Backrooms. Here, amidst endless and haunted corridors, your mission is not simply to survive; instead, you are given a specific task of collecting visual evidence of a mysterious entity, known as Smilers Den. This is a horror game of the same name, causing everyone to fall into a feeling of horror. The horror of this game lies in the fact that the player will have no way to escape. It comes from the deepest desires of humans. They want to escape the pursuit of the demon, but also want to stay and drown in its charm. Will you be able to realize in time that you are in danger? Or will you accept a sweet but painful death?
