Coffee Stain Studios' Goat Simulator might have started as a joke but it quickly became a cultural phenomenon, thanks to its absurdity and cheeky sense of self-awareness. Originally slated for an 18th September release, the Swedish company published the mobile version of the game a day early.

SURPRISE we kind of released Goat Simulator on iOS & Android two days early. We couldn't stay off that "publish" button. It's out RIGHT now! — Armin Ibrisagic (@Arminposts) September 17, 2014

"When you see a big button that says 'publish,' you HAVE to fucking click it," PR Manager Armin Ibrisagic explains on Twitter. Available for the iOS and Android, Goat Simulator will cost $4.99.
