Yes! The versions available to our patrons right now contain epilogues which aren't part of the main game, which is free and will remain free. We intend to sell the extended version here and on Steam within the next few months.

Yes, as well as any other epilogues or scene changes we make in the meantime, and an art pack (although we may sell this separately) which contains full quality versions of the game's artwork. We'll also be offering free versions to some of our supporters and discounts to others (depending on lifetime pledges/donations).
