You DON'T get it? He's got 850 patrons who pay him every month to "support" his so called development, while he just sits back and collects the dough from the horny simps who, for some reason, financially support this blue-ball fest!
There's no incentive for the dev to finish the VN or release any meaningful updates, as in actual sex scenes. So as long as he keeps getting his rent and bills paid by his patreon members, he'll continue releasing worthless updates every few months with little to no sex scenes with characters we actually want to see sex scenes with.
