You suddenly wake up in an unfamiliar room. You step through a door only to find yourself in yet another strange room. This mysterious space is a collection of interconnected rooms, coming one after the other with no exit in sight. What's worse, you've lost your memories. Inside the rooms, you run into other girls who also have no idea who they are or how they got here. But as you keep exploring, you realize something: these rooms are built from your memories. Yours and the other girls'. Who are you? Why are you here? And how can you escape this seemingly endless collection of rooms?(Storyline via IGDB)
