Coming after reading a negative review (won't go into the specifics, don't want to personally insult the reviewer)... Apparently, the reviewer did not approve how the game forced him/her towards incestuous materials.
I really don't understand why some people are so dense. They keep bitching about finding incest in incest games, ntr in ntr games etc. etc. If you don't like the genre why don't you play something else instead of being so annoying - no one's forcing you to play them. And being critical of something you don't understand - that's whole another level of moronic attitude, especially when you realize that the developer has given so much effort in putting together what they wanted to portray - that you are not into it/offended by it is not their fault. Not every person likes death metal and not every person likes classical music. If you don't understand the genre, stay away from it, or at least keep your opinions to yourselves.
Although Haley's story does not have an incest tag yet, you don't have to be a genius to figure it out - Haley is your sister+it's her story+it's an adult game, what do you expect?! And if you don't know about Patreon's crackdown on incest content you might as well be living in a cave by now.
I'm usually not so critical of other people's opinions, but seriously, keep your opinions to yourselves when you have no idea what you're commenting about. I myself never appreciated girl on girl action as much as the majority of the male players, to me it's kinda like a form of ntr, which I don't like either. Yet I don't go bitching about it in every other game that includes it.
Know when to express your opinions and when to reserve them to yourselves, people. It's a big community with a people having varied tastes and expectations, respect them.
