Yeah... small tits, big tits, bimbo, that's three variations for every scene if he wants to do it properly, then there's also that dubious hu-cow stuff in the orc village... So that's four variations spread over two major locations and -story arcs, plus several variant versions of major NPC's...
The dev dug his own hole, probably realizes it, and it seems now spends most of his time catering to fringe requests from patreons while raking in the cash.
The art/models are still good, but story-wise this game is dead, and has been for many years.
In my opinion, his best chance to salvage anything is just lean more into the sandbox scene stuff that he's basically been doing for the past, what, four years? Ditch the idea of a progressive story driven game and just keep adding sex scenes spread over several locations, and be transparent about it.
