Thus it didn't feel like THE end. You've seen your clones, they appeared in the world - and that's it, AFAIR. A very little work was missing.
Would it? The game is nice overall, the missing final level being its only flaw.
Yes, it would be, and would ultimately just be a spit in the face of anyone still supporting the project currently. The game is in an incomplete state at the time being in terms of both story, gameplay, the world, and plenty of other things, for better or worse. Also, I have zero clue where you got word that his wife is doing any sort of "major" work on the game at the time being, as I have literally never heard a single word of that in the last 8-10 months outside of occasionally appearing to write Patreon updates for him.
The work Orexius does is highly collaborative with Anon as well, as each asset has to be approved before it's inclusion into the game, & sometimes tweaked further before it's accepted to be used anyways. While I'm sure he has plenty of his own creative freedom over the project to an extent when it comes to H-Scenes maybe, I
highly doubt Anon would relinquish that amount of creative freedom to Orexius, unless it came to some absolute worst case scenario where he'd be forced to hand the project off to someone else etc due to external factors or something.
There's also the big issue of the fact that this game will be coming to Steam when it is eventually finished iirc, which would probably just gut any sort of chance of Anon working on a second game at that point if he released it in either it's current state, or in the way you suggested as well. I just doubt it ever would happen because he's personally stated that he believes that H-Games don't have to purely be porn fodder, and that's something I wholly agree with and wish more creators would take to heart. Like sure the big boobs & sex is cool but at the end of the day I would still like an actual game.
