This is part of a Patreon post from November:
" 0.6f was on pause cus my ass got in troubles and had to be fixed with love, ethanol and a sharp scalpel. But i'm back from the hospital ( shitty exp to be a patient ngl, try it at ur own risk) and now it's time to make some horny-porny thingies. "
I guess he had problems with hemorrhoids, sitting for long periods of time is not recommended; so, probably due to these circumstances, work on the game is not progressing. It's hard to say, I'm not his Patreon, and DrMolly, who is the only real author, communicates via Discord, but as far as I know, less and less often.
His assistant who tests the game and helps with the translation and occasionally does fan art and actually takes care of communication and discord channel administration, besides that he did parts of the scene with the prostitute but it was removed from the game, his name is Dax, and he probably made the Christmas teaser.
Last I heard was that after 2 years DrMolly will play the game himself. It's possible that he's not happy with many things and is working on fixes. He seemed a bit bitter with the fans' constant complaints about grinding, who knows, maybe he just got bored with it all.
