I will be continuing to update the existing Acts for free, here. The final Act will be delivered to Patreon/SubscribeStar supporters, and those who buy the game on Steam. I'll also look into making it purchasable on Itch, for people who are region-locked!
Patreon & SubscribeStar give us enough to keep going. We've decided to launch on Steam so that we have the ability to finish the game faster, to reach a broader audience of dragon fans, and to enable people who want to support our development but can't or won't use subscription services.
