Black Walls

Joshua, a maintenance technician stationed on a lunar space station, is separated from his crew during a routine mission and left drifting alone through space. Beyond the dark side of the Moon, he discovers a colossal structure of towering black walls unlike anything built by humanity.

Drawn into its endless labyrinth, Joshua encounters impossible architecture, symbolic objects, and unsettling traces of someone who looks exactly like him. As reality begins to fracture, every step forces him to confront echoes of his past, the choices that shaped his life, and paths that have yet to be taken.

Explore a silent, impossible world of puzzles and obstacles. Make symbolic choices whose consequences may not be clear, your decisions shape your ending. Choose Chill Mode for a calm, mysterious journey with nothing hunting you, or Horror Mode for fear, danger, and something that wants you dead.
