Honestly really good game 8.5/10.
Sound/Music: Really like how you incorperated different soundtracks for different scenes with sounds effects such as zipping down the pants to sfx in sex scenes. However, the sound effects for sex scenes can be used throughout the duration of the scene rather than having it only "appear" when transitioning the pace. 9/10
Animation: Top notch, love the fighting scenes and interactions with the characters. The characters are fluid and has levels of physics involved. Definitely a 9.5/10 on this part and can improve on the emphasis of bodily fluid, hair, and human features such as wrinkles.
Story: I do love the MC revange arc and his narcissistic personality disorder due to the lack of affection hes gotten since childhood. Maybe the story can have possibility of having flashback moments to see what really drove him into thise exaggerated feelings of self-importance and his increase of sexual desires. But I do love the story of the MC level of black-mailing and his keen of manipulating the characters but the "drive" can be emphasized more. 7/10
Again overall solid game and has a lot of potential of hitting that 10/10 score.
