Well from the Angry Joe interview they said they update it weekly so i assumed that it was out already.
The devs update and play the game among themselves. Founders get access to a simplified version for play-testing beginning in fall. (Actually, Founder's Access is split into 3 waves, depending on how much you donated.) By my estimate, the real game will come end of 2016 the earliest.
The full game is not out yet you will get an email notifying you when you can download and start testing. Also please do not necro old threads.
