If you're at all familiar with the indie game scene in recent years, than the name Jonathan Blow should be very familiar. The man behind 2008's Braid and 2016's The Witness gave a talk at the Reboot Develop conference and showed off a small sample of his next game.

The essential showing of the prototype was a character on ice pushing around a block, which aside from being something that Jonathan Blow has worked on, is not too exciting. Blow did say that the game was very early in development but that it already had about "25+ hours of single-player gameplay."
