"That'd be fun," Blow said, noting that it would be a challenge for such a project, just like his MMO concept, to be considered an art game.

"It has to be an art game in a different way. It can't be an art game in the cinematic way of 'you walk in and here's the final polished expression that's very tailored' which is what [The Witness] and Braid are," Blow said. "But it can still be an art game in the sense that we're really going for something specific in the systems that we're building. The more experience as a designer I have, the more I'm interested in that part of it."

The Witness will be released in 2014 as a timed-exclusive for the PS4.
