For the price I was expecting much less. This is the marvel of visual novels; they are built mostly on visuals and writing, and both aspects are very important to value the overall experience. Probably the reason the buy price was so low is because the visuals are not too great. For the writing, it's well worth the investment.
There are 2 pages of CGs for a total of 15 illustrations of not too great definition, but good enough imo. The drawing quality is good for the bodies, but I don't like the author's style for the face of the protagonist, although I can see it must have tried to convey an older, more mature woman face. I think mature women, specially from asian countries, can be very pretty and even not always represent their age. You can check the gallery to see what CG's you're missing. Hunting for CG's from alternative story choices is extremely easy and fast. All choices lead to endings soon after, and the only story branch that has subchoices is the main, longer story, so you don't need to skip the whole story for the alternative paths. The game has the normal pixelization of genitals you see in JAVs and original japanese eroge content. I know many people can't tolerate it, but I can. I care about the erotism conveyed in the narrative, scene, illustration, presentation and concepts in play, over the clear visibility of genitals.
The story got me very surprised and many levels, and GOG also surprised me. I heard GOG went woke and all, and that may be true for stuff that matter in the PR department, like the hiring policies, but when talking about the games, they select really good titles, no matter how controversial the concepts involved are.
Without spoiling I can tell about the concepts the VN plays with: It talks about racist biases from japan towards black people and foreigners in general, and the racist biases of the world against japanese men and women, both in culture and biology. It also talks about the psychological force of sexual pleasure.
