The animation and art direction are incredibly good. Everything is pretty aesthetically pleasing and the live-2d style animations are surprisingly fluid and expressive! This is about the pinnacle a japanese hentai novel can achieve because, as usual, the writing and character development are complete ass.
I have a theory that japanese people don't understand human nature on a basic level, and so things like motivation, pacing, risk vs reward, needs vs wants, are all over the god damn place here. Characterization is so haphazardly constructed that it feels like the MTL robots wrote the game to begin with. Normally you can get away with this stuff in most porn, but character motivation is vitally important for NTR specifically. The fetish entirely revolves around the WHY and HOW sexual encounters occur. It's uniquely difficult to portray through visuals alone and so relies so heavily on the writing and characterization in the story.
Yet another frustrating case of the japanese forgetting how humans work and making an expensive well produced game where bi-polar schitzo dolls get raped by a psychopath meathead and call it NTR. The only person getting NTRed here is me, cause I had to suffer through this excruciatingly long game to get blue balled anyway.
If you like rape and hold your down arrow until the characters stop talking, you will enjoy the 5 animations this game offers. Or you can go to pixiv and save 8 hours.
