The Witness is a game currently in development at Number None Inc., the studio established by Braid creator Jonathan Blow, for the PlayStation 4, PC, and iOS. The game is designed to be an open world puzzle game. The goal is to set the player on an island with things to do that take no more than 20 seconds of travel to reach. The developers have attempted to create a tight user experience by cutting out anything that isn't necessary but the game is still expected to be around 25 hours in length.
