Wow, where to begin? The game is well developed, which is a nice, welcome change for a "new" (I played only until Day 2) porn game. The main character's thoughts and motives are well established. Some other characters are well thought out as well, while some others seem to have only one personality trait. The sex scenes are nice, if not overly detailed. All in all, a good new game.
However the text and the interactions are SO CRINGY! There is some heavy used of romanized Japanese in the cringiest possible way. It's like the author is trying to show off his knowledge of the language, but it's uncomfortable, it's tacky, it doesn't reflect the japanese culture and it certainly doesn't help the game. Not many games can brag about giving me a physical sensation of disgust, but the way the japanese language is used succeeded in that.
The other cringe factor is the inclusion of underage characters. I'm not sure yet how things will evolve but a 32 years old man in a position of authority having sex with kids is definitely wrong. I hope the game doesn't stray in that territory.
Also, the fact that the author is not a native English speaker is clear in the fact that some of the dialogues would benefit from a rewrite or some edits. It's not as bad as some low-quality russian games, but it's far from perfect.
To finish on a good note, the music is absolutely fantastic. It's of a much higher quality than other pieces used in other games and strangely addictive. I could see myself listening to the music from this game while doing some chores.
In short 5/5 for the amount of content, 3.5/5 for the sex scenes, 5/5 for the music, 1/5 for the cringe factors.
