Plot
The game has a minimal story, in which the player is told by letters of a mysterious box in a room in a house; as the player solves the puzzles around the box, more notes from the same author - one who previously had solved the mystery of the box - are found, describing the box's use of an ethereal material called "Null", as well as showing the author slowly descending into madness.
