Edit: Lots of spoilers below.
In the plus column it tries several new things with the incest genre, which is admirable and it's good to see developers trying new things.
1) No dead dad or uncle, no romance with mom and 3 other sisters. It's just the sister, and it's been a long time coming (which plays into the fantasy of someone having been into you forever and ever, and is satisfying, especially if they seem to be cool and are attractive).
2) No return after 7-10 years. They've been together the whole time. This takes more work to build realistic relationship with ins and outs and preferences and annoyances, which they do pretty well.
3) Gradual and believable romance/attraction, well written, including jealousies and natural progression over time. One of the best of any game I've seen, with the little things that make up a traditional romance. This is the best thing about the game, honestly.
4) Deals with uncovering old secrets once the romance blooms, including sex abuse, like is often the case - new confidence/security in a relationship brings out trauma from previous relationships.
5) Deals with the aftermath of sibcest with the parental unit who figures it out.
6) Smart, interesting love interest - Haley is fun and interesting and unpredictable (for a good part of the game).
7) Uses a crossover with another game as a key plot point, not a guest appearance.
8) Follows through on how oddly other people feel about the sibcest, and the sibs come across as creepy in threesomes, "Join us!" A freaked-out third point in a triangle that includes siblings seems more realistic than, "well, there's an erection, we better do something about it."
9) People actually have jobs and things to do and those aspects are part of the story too, compared to stories that are like, 'well, I'm between sexual escapades so I'll watch TV.' Work is integral to the plot of them staying together, of the relationships that they build, and of ways that their personalities come out.
10) The MC isn't a dick. He's a normal, nice guy who watches out for his sister and is generally nice to people.
11) Most other males in the game (and there are other males) are not predators/psychopaths or clowns. They're just dudes.
In the minus column (related to the numbered items above):
4) SA: Breaks the problem well and semi-realistically and then deals with oddly. We don't actually know what happens in the end (if you've played Alexandra you can guess). How they bring in the characters from Alexandra is kind of cool, and re-emphasizes those character's personalities. That's cool. BUT! It's a lot of build up and I felt frustrated and protective of Haley (well done) but then it just disappears and she doesn't ever find out. She gets closure through therapy, which is cool, because it doesn't go as planned either (cool). It was unsatisfying. It's a complex topic and healing/resolution is going to vary from person to person, and maybe folks don't want to wander into that, but if you're wandering in, you know. Wander out, don't just turn the lights off.
5) The whole getting a new apartment and then trying to hide it from dad was where I started skipping, it felt extraneous. 1-2 interactions and hard conversations and then let's be done. To be fair, I can't think of a lot of interesting ways to drag out 'Dad found out we're banging' but it is realistic to think they'd get found out eventually.
6) Haley does seem to change personality in the third act. It's funny writing but it's not consistent with who she was earlier.
8) The throuple endings are not very satisfying, the third wheel always feels sort of sidelined. Maybe that's the point, that it was always about the siblings, but it came across as underwhelming. With that much build up the big things that happen later would feel more satisfying if they had more heft.
