Joel “Deadmau5” Zimmerman is in the very early stages of development on his own game and, although he doesn’t want to talk much about it, the musician did stream some early alpha footage on Twitch.

“Mad early ‘alpha alpha’ testing ... but making great progress with the team,” Zimmerman tweeted. “For now, consider it a pet project ... give us a year at least.”
