Hey, nobody's linked the game's homepage:

Tip for Euros: When buying through the humble store, you not only leave more share to the author, but it is also cheaper than buying from Steam. I paid 7,77€ (the nice sum might be paypal's currency conversion); Steam lists the game for 8.99€.
Steam keys are also included in the Humble Store/GOG versions.
I'm very happy that the full game includes a sandbox mode. The normal game goes over the course of 31 days and includes 20 different endings.
According to Pope's Twitter, the game isn't released until noon Central European time on GOG, the Steam and Humble versions are released at 10am PST (19h CEST) - no midnight passport stamping for us.
