One of probably the most surprising things about Sony’s big PlayStation 4 reveal was just how much Sony appeared to embrace indie game developers. The physical manifestation of this commitment was Jonathan Blow, the developer behind Braid, up on stage on the presentation announcing that his next game, The Witness, may be coming to PlayStation 4.

Since that point no much have been revealed in regards to the Witness, though Blow did promote the PS4 with a developer conversation video back in May. Today, Sony teased some information about what to anticipate with the sport.

The Witness might be an open-world puzzle game, though players can be shepherded from easier puzzles toward increasingly complex and mind-numbing puzzles. Players will walk or run across the lonely game world until they approach a puzzle and enter a “draw mode.”

Once in draw mode, players will solve what looks like an easy 2-d maze puzzle, drawing a line from the start of the maze to the tip. Though the puzzles will start off relatively straightforward, they are going to quickly advance, adding new rules and becoming harder. Anyone who has played Braid will know just how far Blow can take seemingly simple game mechanics.

The process may be seen within the gameplay video released earlier this year, though even seeing puzzles being solved doesn’t necessarily spoil how they’re solved:
