I think Shota content will appear further down the versions. Not as of right now. It seems Techno wants to expand content in the City for the time being. Which is a good idea.
I think either you're confusing "Release" meaning "Full Release", which is 1.00 version most of the time. Or either he changed his plan and thought of implementing the Futa Follower later at some point.
Yarizo is a big man. So i'm kind of hoping if he's gonna implement a Futa Follower. Should be some towering axe wielding mean looking woman hiding a destroyer package. That'd be fun for a change.
As of now. I'm pretty sure he's expanding content at the City, and then he may start developing further out, prioritizing places he can overlook easier. Keep in mind the Casino was overlooked for a rather long time, it seems. So he felt like working it out and finishing a good deal of content there so it's not sitting there and gathering dust.
Oh. Um. Will the saves function on the new versions? I didn't see he said the saves would break in 0.38 or 0.39.
