Overall the game has interesting sexual themes and a decent premise for a sex game. However, the premise is let down heavily by both the writing and the art, and the sex scenes themselves are oddly truncated and undeveloped.
Visuals
The main barrier to enjoyment is the ugly, inexpressive 3d models. The sparse list of screenshots on the f95 page look almost comically inept, and can easily give one hte idea that the game might use animations, and that the screenshots, though bad, are not accurately representative of the game as played. This is not the case. The whole game consists of text of static pictures.
While low-quality models can sometimes be appealing because they allow for a high degree of expressiveness, this is not at all the case here. The expressions are wooden and often difficult to read. As a matter of plot, the expressions change depending on how brainwashed the characters are. In one short "bad ending" path, the main character goes overboard and fries to brain of the main female character, Rachel, leaving her essentially braindead. But the storytelling falls completely flat because all the characters look like braindead meat puppets and all times. The different eyes which are used in an attempt to convey emotions range from scary 1000-yard stare to slightly less scary 1000-yard stare.
Writing
The writing suffers from an extreme case of telling over showing. This is cliché, 101-level writing advice that isn't always really applicable, but this story is a great example of how telling can go way overboard. The main character will have a conversation with one of the other characters, then immediately go on to describe in detail how they feel about the conversation, how their childhood impacted their view of this subject, and what the wider themes are. It comes across as ridiculous, and it's made worse by the strange moralistic tone that tends to creep in at weird times. It's hard to take seriously the main character's meditations on Stalinist agricultural purges when they're being told to the sexual trafficking victim that he made his mind-controlled literal slave bring him for his own sexual gratification.
The writer should probably take some creative writing courses at a community college or something. But maybe don't workshop this specific story or they'll try to have you thrown in jail.
The sex
The sexual themes and ideas are by far the strongest part of the game, and there is some interesting stuff in there. The inversion of the dominant-submissive relationship that is a core part of the premise, especially early on in the story, is not super original but always a welcome concept. Whether you like the fetishes presented is obviously subjective - I find the anal focus, the bondage and the domination stuff to be spot on. The daily outfit butt plug stuff and the sensitivity lube stuff is all really great.
Unfortunately, none of this is explored in any depth at all. While the game is happy to talk in detail about the characters' feelings about sexual domination, enslavement etc. for great lengths of time, the sex scenes themselves tend to be extremely short and underdeveloped. Some of the plot points are just dropped with no pay off. The sensitivity lube is used in one path to heighten the long term anal sensitivity of Rachel, and it makes it seem like we're going to be treated to a view of how she develops and accommodates this new reality. But instead, it's referred to by Rachel once as impacting her life in a fairly anodyne way, and then the main character simply stops making her do it, and we never hear about the lube again. Similarly, in multiple paths the main character directs the girls to wear butt plug as part of their normal outfits, but we then never see them interact with anyone other than the main character, nor are we given any real indication of how this affects their day to day lives.
This is a shame because bringing sex scenes with interesting kinks is the game's real chance to rise in quality beyond its weak fundamentals, but it never really commits to it.
Structure
The game is structured not like a western trainer or sandbox game, but rather like a classic visual novel. The interactivity of modern western porn games often give them a leg up on the better produced Japanese porn games industry, but in this game, that's not utilized. Player interaction is extremely limited, simply choosing one or two options, which then lead down different, mostly kinetic story paths.
