Well its only a prototype, and seeing that its being years since its last update i can only guess the creator of the game has no intention of working further with it.
I could also be wrong since there is Discord for updates. (But then again, most people on discord dont really have access to your content.)
Kinda feels like I wasted my time providing feedback for this game. Correct me if I'm wrong but last I heard this game is no longer NSFW which is a shame. It's like why get us excited for a game with a good direction just to say "nope, changed my mind". Just picking at a skeletal remains of a horse with a stick at this point.
