I read a comment by the dev himself about removing
Looks like a technicality: let's put barely anything that we can call incest in the game to just put the incest tag and drive people in, even when it doesn't even involve the MC.
I remember the dev of Alison fallo of the apple, had an incest tag at some point, and I made a comment about that. The dev was honest enough, without being asked, to warn me that the game had little incest content and it wasn't the main theme. Later I saw they removed the tag entirely. (the dev made another game with incest that's very nice).
Anyway, I just make a comment about what I experienced.
That's right, that technicality, that inkling of incest provides deniability about the absence of incest as a theme.
It's not gonna happen, but it would be hilarious if Patreon would ever object that as incest content and make them remove it.
