for this one, I'll consider it from two aspects, the visual novel and the translation, it will be a long one.

VN: the thing I noticed firstly, the pacing.. can get a bit jumpy and fast, even some endings or events are unexpected, can feel abrupt especially in the beginning, and I still don't understand some of the exorcised souls, matsu(kami) god or whatever, though the mystery and story still manage to get resolved by the end with a true, happy conclusion. (Small nitpicky thing; the song Kagome Kagome played during whenever the third matsukami/kokeshi god I think is unsuitable.) It's a nice surprise that I didn't anticipate for Ryuji to be responsible and kind since I thought he would be evil/mean towards Yoruichi. Now if we talk about the yandere—star of the vn; Yoruichi, I can state for sure that he's extreme, in a way he would.. um, get so quick in resorting to assault and/or rape the heroine what with the drug abuse hypnosis and everything, I wasn't quite satisfied with the way he treated the heroine honestly, but he did give me the rightful chills, horror and disgust. Plus, the lackluster heroine barely had a soul in her, and since this VN was the type of blank slate protag whose words only gets spoken through other characters in that meaning, she was more of the doll at this rate rather than Yoruichi besides the moment she has to purify the matsukamis and the reveal about her at the end where she could've just talked and prevented worsening the trust+abandonment isssues she give to Yoruichi way earlier. It does give off the amplified disappointment despair for the bad ends though, haha.

Translation: I found typos (particularly the quest/quess/guess-guest words), incorrect use and discrepancy of grammar, and some untranslated words in Russian with all them combined it can get quite distracting and confusing at times throughout the gameplay, but I do still appreciate the efforts to translate this from native language of Russian which I think the translation team was originated to English done for free of charge. But the most glaring issue for me was, for the page of this to be lacking any warnings whatsoever beforehand since this one is... quite NSFW, can get traumatizing especially for those who don't want to get exposed to some specific themes like that beyond their initial/vague expectations.
