I'm convinced they're just openly trolling their community and testing how far can they get away with while laughing their asses off at their patrons. No way this will ever be finished.
It's clear in the beginning of the "rework" that they lost or fired their artist and coder, and have been patchworking some lame stopgaps with AI. I mean, the new artist got busted multiple times by pushing out images that had clear telltale signs of AI (extra fingers and shit).
I think somewhere along the line they realized they could get away with basically never updating the game and they'd still make a reasonable income. But I also think at some point they got cocky and just started to see how far they can push the subscribers. Or maybe they got annoyed with being called out for their lack of organization and updates.
Either way, the end result is almost definitely a troll, and you need only look at the content they have put out to realize that. Every update they push is Live2D shit from old content, or new images where the MC fucks an old women or a goddamn gremlin.
Or maybe the product they're now selling is some weird crowdfunding-edging kink. Like FinDom, but just as pathetic.
