I think it's a controversial game, and I've considered giving it 3 or even 2 stars, but when really evaluating the game, I'm willing to give it a 4-star rating.
First of all, I don't think this is a porn game in the traditional sense, there are very few sex scenes in the game, which is about the same as none; On the contrary, there are several huge texts, and people who are unwilling to read and understand the plot should not be able to play it at all. As a game, players cannot change the flow of the game at all (except for choosing missions), in other words, there is no gameplay at all. The whole game is really just a visual novel, or comic-like, where you look at pictures and read the text.
Secondly, due to the unique theme of "Hentai Prison", the atmosphere and language in the early game are very oppressive and violent, which is not easy for new players to accept.
As for the reason why it received 4 stars, it is entirely thanks to its text. The plot of this work is rich and unique, the various contradictions are very distinct, and some reversals are also surprising. The characterization of the protagonist and supporting characters is also very full, especially the male protagonist, which is rare. The UI interface is also very exquisite, and you can see that the production team has made it with heart.
Of course, the shortcomings are also obvious, for many contradictions, the solution of the protagonist group seems to me like child's play, not reliable and rigorous, emphasizing novelty while losing shock, it seems anticlimactic. In addition, there is really too little CG, who will make up for the Noah piece I am missing (crying).
That's it for the evaluation, if you are a person who likes to read and focus on the plot, I recommend you to review this game. On the contrary, if you just want to find a picture to satisfy your desires, you can say goodbye to this game.
