Jonathan Blow's next project sounds absolutely massive. The Braid designer and his team are currently putting the finishing touches on The Witness, an open world puzzle game coming to PlayStation 4 that is reportedly somewhere in the neighborhood of 25 to 40 hours in duration.
That's a far cry from the eight hour campaign Blow envisioned when he embarked on this journey. In a recent update on the PlayStation Blog, the designer suggested the title might just be "the biggest and most-intricate world ever built for a puzzle game."
In addition to detailing The Witness' massive environments and tweaking its puzzles, the developer is presently focused on creating a "smooth and solid frame rate, making the graphics look as nice as possible, and ensuring that the streaming system loads things quickly."
