Look, we can all agree that Patreon should get double-fucked with a both a fire hydrant and a rusty garden weasel for pulling the rug out on its adult-oriented developers the way they have, but at this point, it's hard to be sympathetic for devs starting games with titles like "My Lovely Daughter." If that's the game you want to make, you're gonna have to find a different platform (unfortunately, not many alternatives exist) OR give it a discreet title and avoid the TOS violations while also working on a patch that restores the "forbidden" content. That's just common sense. You'd have to be pretty ignorant to start developing an incest-themed game with the plan of hosting it on Patreon.
It doesn't matter if this game currently contains no incestuous contact.... Either father-daughter shenanigans are the goal in the future development of the game, or the main female nonMC just happens to be the daughter of the MC but nothing happens between the father and daughter so... then what? The player has sex with other girls while the daughter just exists, oblivious? We observe chastely as the daughter engages in sex with other male nonMCs? Uhhhh, neither of those sound too fun, at least to me.
It's sad and maddening and unfortunate, but we live in a post-Patreon world now where these games just can't exist on their own. That sucks, but devs who ignore that reality are being pretty blind to it. Other devs have shown that it's not all that complicated to disguise a game and provide patches that restore the original intent.
Hopefully this dev is smart and creative enough to rework the game so the daughter is some "family friend" or something needing a place to stay, and a patch makes everything right again.
