I think the problem is, you cannot get both a funny realistic story AND an one about incest
To get both -realistic and about incest- you got to write an horror story basically, so the MC is some psyhopathic abuser and the girl a psychotic victim, and as soon as any other character know about it ends.
They started with the idea of a game about incest bs, but then they did a fun story with realistic characters leaving the logic behind, either because Patreon or (I think?) they changed writers and the writer was good writing realistic funny girls (and you can't go realistic about incest without going into horror so the incest thing was lost in favour of fun)
Imo the only way to fix and make the whole thing work is either by erasing any incest bs of the story, or, just enjoy the game for the dialogue and funny and realistic girls and pay no attention to anything else
What are you thinking of, posting a sexually unexciting, TOTALLY SANE post like that?
Seriously though: I think there's much sense in what you say.
Another conflict too, surely?:
Clearly, many players, & crucially patrons of "adult" games get a serious thrill out of (you'd hope, only fantasy) inc*st - consider how many games have an unofficial, in some cases even official "patch" created for that purpose, to get fam'ly terms into the dialogs as much as possible! - so there must be a strong press of demand on developers to include it, at least as an option, if not central to their game.
I have to admit, "roll your own" (even the smoked variety) is not a turn-on for me - I'm not being virtuous here, or even thinking mainly of practical legalities: just, I don't really see the point of looking inward too much: even in fantasy, why not widen the circle to people different from yourself? - so I came to this game with a slight contortion of the mouth at the original title.
But I saw the quality in the graphics, e.g. the first two smiling, lounging, coolly smoldering girls, who didn't at first sight look much like sisters ..., & the description of the storyline (for once not a MC tragically orphaned at age 12, etc. ...), & that looked promising.
What's maintained my interest has been: (1) super artwork - the girls' *cough* well-rendered & -textured *cough* bodies most of all - (2) light-touch, (in a good sense) sophisticated, witty, sometimes sultry dialog, (3) plot winds & meanders that are (for the most part!) involving, & again (4) for me, the game's twin peaks, Heidi & Kathy - two top creations, both as sexual beings and as engaging, likeably crazy-but-not-so-mad, generous-spirited (!) characters with elements of personal depth unusual in games of sexual content. Realistic, even, though more forgiving. But in a game without the unavoidable agendas, dissatisfactions and/or frustrations, daily pressures, banal necessities or worse hardships, & human cost of real life. (In a word, "fantasy".)
So basically I'm agreeing with your last sentence, too!
