0.7 Schoolmate:
So, to balance out the previous, failed attempt of an extreme NTR moment, the developer implemented the option of a lovey-dovey route. Hopefully, it will feature NTR in the future, otherwise he has to change his name to "1/2NTRMAN" or "NTRMAN, unless I'm not".
The other half is a blackmail setup that's immediately forgotten because it's too hard to write. She's a slut. The End. Man, I really wonder how the next chapter or game looks like. Will the next woman be a slut just like that? Who knows! Everybody before that surely was. NTR, man.
0.4 Mother:
Hm. From the son's perspective, everything is as basic as you'd expect and that's quite underwhelming or becomes annoyingly obvious at times. The revelation is quite 0% to 100% (caring mother -> slut who doesn't like you) and since the son is as baffled as the player I suppose, I'm not sure where the developer wants to go with this.
The mother's perspective makes a lot more sense in the beginning and I'm actually surprised by how smoothly the first sexual switch is displayed. But it kind of goes from there - the essential
purity vs. depravity dynamic is mostly missing and the revealing moment remains poor/out of place.
The "inner slut" approach can be a nice asset but it shouldn't be the entire story, that's lazy! It works if she lives two lives, it works when the son becomes a necessity of it, it works as just an element of corruption or can work as a character background, but this alone does not form an erotic story. Or at least a creative one. It's just things we've been seeing before and maybe even will, over and over again, from a certain someone who didn't have enough clarity or patience for a truly good Adelaide Inn.
Visuals are still good enough to reach 3/5, voice acting's there, presentation, gallery, a little wink at his other game. I mean he tries, I guess.
