Let me preface this by saying I've only played a single route, so may have missed some cues.
This game feels really natural, and I feel like I can compare this to "Parental Love" by Luxee, which has some similar traits. Models and scenes are high quality work (improves as days pass), and I'm already in love with both of the main characters, both their personality and their "personality". Kappa.
The daughter is drop dead gorgeous. Fact. And the mother is pretty good looking as well, but I know who I'd pick if I had to choose.
Also the fact that at 18, the daughter knows about MALE GENITALIA, SEX and MASTURBATION. Shocker, I know... Other games such as "Big Brother" and "DMD" approaches this a little differently, and I'm glad MSN decides to go this route instead. As in she knows about these things, not like in "DMD" (absolutely clueless, almost to a point where it's annoying), or in "BB" (not completely, but still needs a lot of guidance).
I usually hate the "cringey" introduction between characters that a lot of games, in my opinion, struggle with. Although not perfect, this definitely checks a lot of the right boxes. Spelling and grammar mistakes also grind my gears, and this game has a very limited amount. Big plus! (I'm looking at you, "ha ha", this one triggered me immensely several times, but personal preference I guess.)
Also, the facial expressions and the small attention to detail is exceptional. Having their eyes/eyebrows/smiles dictate their mood is executed perfectly, and I'm absolutely torn when the daughter blushes. Too cute.
Having written this review, I can't think of a single thing to point out that I don't like. To me, it's that good. Instant favorite, leaving me wanting more, with "Parental Love" trailing not too far behind. It may be personal taste, but I've played many of the hyped VNs, such as "DMD", "BB", and both of Ptolemy's creations to name a few.
TL;DR
Instant favorite, second to none. Similarities to "Parental Love", and I love it because of both the characters and the natural feel of the game.
