This is a typical story about a female character who, as a result of her actions, takes the path of corruption. Even if you read the description, you're unlikely find anything out of the ordinary that you can hook on to. But anyway, even if plot don't sounds unique execution can fix everything.
But not in this case, unfortunately.
I must say I usually skip games where I'm not interested in the description or do't like the screenshots. In this case, I was hooked by 2B in screenshots, yeah that's right, there is that juicy ass that almost any gamer will recognize. But here she have another name, and she is not related to Nier universe in any way.
Story/Characters/Dialogues
Story:
Typical story about student girl who want to try something new and diversify her life with various perversions. But there is a problem, she start doing it out of blue, without any good reason for it. Her corruption feels artificially created, usually in this scenes, there is no good mood what would motivate her for decisions she make, or strong events in her life, she just do it, because one day she start to wanting it. It feels like she was good girl her whole life and then boom! For one week she can turn in sperm bucket.
Dialogues in this game slightly better than the ones you usually see in porn. Not THAT terrible, could be worse, but they plane and boring, you don't believe in them.
Characters:
Jock boyfriend who doesn't have much personality, and easily cheat on MC because she not perverted enough (Well he doing it with 2B, so I can fully understand him. So maybe I don't even consider it as a minus for the story
)
Slutty girl friend who drag MC down to path of corruption.
Perverted father. Well not really that perverted, but interactions with him is easily readable, and I'm not will be surprised if MC will have sex with him after 4-5 interactions (so there is no depth in their relationship)
Perverted neighbor - nothing said about him, he just here for sake of cheating on MC's boyfriend and exploring corruption path.
Boyfriend's brother - I didn't payed attention to him because, when we encountered him, I was already got bored, so nothing said. As I understand he also for NTR purpose.
2B and her slutty friend - They going in the same school, and they put eye on the MC's boyfriend, so they are revivals for her (2B also playing role of a slut here)
Overall characters don't feel memorable, they pretty typical, and poor dialogues only make it worse.
Conclusion: 1/5
Visual side - Graphic/Animation
Character emotions:
Usually you see static face, no matter the situation, or cringe expression, or another kind of weird facial expressions.
Renders:
They are really good, for me it was one of the reason why i wanted to try this game. Texture of woman genitals also much better than in most HS based games.
Animations:
They are good. Some of them default from HS engine, which is just fact not minus and I'm not really sure if there's a developer's own animation here, but it seemed like that, anyway overall they're good.
Conclusion: 4/5
Gameplay
There is not much to say, we have story in which we dive in, story progresses, we choose one variant from several, moving on. There is hidden stats of corruption, so if you don't get enough points, which could be obtained by choosing perverted choices, you would't have opportunity to pick another option.
Conclusion: 3/5 (Nothing new, typical vn gameplay)
Final notes. Under normal circumstances, I probably would't write a review for the game which is on early stages of development, but this game have deep problems on one of cores of any vn game - story/characters/dialogues.
In the current situation, you just can't immerse yourself in to the story, because it's bald and uninteresting and characters don't feel real. And I don't see the possibility to fix this, except to rewrite everything from scratch, which won't be the option for dev, I presume. Anyway, if you don't care much about the story or characters depth, I think you can find here your fap material, because as I wrote above, animations and renders here are well done.
