The Witness designer shows off prototype of new game

It looks like we'll be pushing blocks around in Jonathan Blow's next game.

The Witness designer Jonathan Blow has shown off an early prototype of a new game. While not official in any capacity, the unveiling happened during his talk at the Reboot Develop conference in Croatia. Thankfully, it was livestreamed on Twitch, so we're able to get a look at it as well—it's been uploaded to YouTube by Daniel Bross, and you can see it in the embed above.

It looks like it's a puzzle game that consists of pushing blocks around. According to Blow, it's still very early on in development, as most of the work has been focused on creating the level editor and engine, which will be made available to other developers for free. He said that he "should make and ship" a game on this engine, so we could could end up seeing it come to fruition. And apparently, he's already thrown together more than 25 hours of single-player gameplay, but he noted that it's unpolished and the visuals aren't final.

It might be a while before we see or hear anything else about this untitled game, but we'll be sure to report back when something is revealed. Blow's last two games, Braid and The Witness, were both puzzle games that garnered many positive reviews. In fact, The Witness received glowing remarks from critic Edwin Evans-Thirlwell in PC Gamer's review.
