Like many PC games, The Witness sits in my Steam backlog begging to be played. It's a beautiful exploration based puzzle game that was one of the top rated indie games of 2016. One downside to the documentary is that it contains a ton of game spoilers. That said, if spoilers don't matter to you or you've already played the game you really should watch this documentary. It's a great focus piece on the game and Jonathan Blow is a game designer I respect and is always fun to listen to.
