The Binding of Isaac is two years old, and in honor of the anniversary, creator Edmund McMillen and the team behind Indie Game: The Movie released a short documentary about the game.

The documentary is among the many bonus videos that is included on the special edition of the film that was recently re-released. According to McMillen, this 30-minute documentary covers, "basically every detail about creating [The Binding of Isaac] and its message."

You can check out the documentary below, and you can also pick up the game from Steam, which is currently on sale for $0.99.
