Hey Geer!
V0.8.08 is currently in Early Access over on Patreon, so the game fairly far along. I'd say there's around 30+ hours of content right now.
Itch have changed how paid adult content works here, so we no longer offer that option unfortunately (we would like to bring it back if Itch reverts changes).
A House in the Rift is free, and all future versions too. It just takes a little bit of time for those free versions to be released.
