You're in a hallway, in a basement, in a house. You have no memory of who you are or why you are here. Exploring outward, you find yourself on a strange island, full of puzzles, which are placed in themed areas: a castle, a desert ruin, some kind of hybrid laboratory-art-gallery. Here and there you find audio recordings, narrated by someone who seems to know a great deal about this island. Is that guy responsible for your situation? How did you come to be here, and how can you get home?
