Game developers on Twitter are sharing what their games looked like mid-development

Video game developers are taking to Twitter this month to give the world a peek behind the development curtain with #blocktober, a hashtag that level designers are using to share early builds of their levels.

It started with Michael Barclay, a game designer at Naughty Dog, sharing a level blockout (basically a simplified layout of a level before all the cool visual details are added in) of a level he built for practice at home.
