Ok, so, I've had a lot of fun with this game at the beggining, but for the last couple of levels things have just not really made much sense with the way the characters interact with one another.
I really like what this game is going for, with the slow and restrained aproach to corruption which looks a lot more realistic than other incest stories where both parties just immediately give in and from that point onward they just fuck. It makes sense that it would feel unconfortable, and wonky, and that the characters would be constantly worried about where each other's boundaries are, and that's great. But I'm afraid the game is just not well written enough to support it, and instead of comming across as realistic and emotionally engaging, it is just completely overbearing.
We get it, the mother has never felt loved in the past, so she needs to be constantly reasured. It's a good character arc to have that character slowly ease into the mentality that she is loved, beautiful and hot but...she has to progress. She can't keep being shocked, in the exact same way, every single time. I've lost count of how many times she has said "No one has ever said that to me", and that's not a line that works multiple times. Someone has said that to her. We have. Multiple times in that day alone. Other similar lines are also repeated constantly. Most damming of which, altough not exactly a line, is "chuckles" or "giggles". Whenever characters aren't completely freaking out about stepping over a boundary, they're giggling in every other line of dialogue. No one talks like that.
Sister is even worse, because though she suffers from all the same problems, her's are never justified in the story. She didn't have to settle with a guy she didn't love and raise two kids. She hasn't spent years alone, longing for love. Her need for reasurance is only slightly explained by her body image issues, which are once again, not well written enough to come out as endearing. She doesn't like her breasts because...reasons. And her dislike for them isn't reflected in how she dresses, nor does she feel self conscious around her own topless mother no, she only dislikes them when the mc says he likes them, and then she finds thousands of reasons why they're bad. Because then the MC can be "sweet" again.
"Hot scenes" being interrupted in that way are the rule in the whole game. Every intimate moment is interrupted by the characters shifting their focus to something that happened off screen, years ago. That's actually a great way to paint the image that these characters are not very confortable with the situation they're in, and are trying to ground themselves. It would be good writing, if it wasn't once again overused to shreds. Eventually they have to be comfortable with one another. Their relationship dynamic has already been well estabilished enough that we don't need these moments for it.
The story is good. It really is, it's a lot more engaging than the mindless fuckfiesta of games like Corruption. But the writing is abysmal, miles below other games with the same approach, like Dating my daughter, Freeloading family, Summertime saga, etc.
And once you start getting bored of the repetition and start skiping nearly every line of dialogue you're left with nothing. The art isn't good, and there is barely any gameplay. Those two things wouldn't matter if the game was well written, but since it isn't, the game wasn't an enjoyable experience.
