A minor thing that could be something to consider... Every instance whenever MC cums, there is absolutely no build up or awareness that he has climaxed. No close-ups, no text or dialogue, just a silent instant finish and maybe showing some cum after that. It is kind of disappointing that the game literally SKIPS the point of ejaculation entirely.
It would be nice if any or every time MC is with someone or alone - that he has some sort of dialogue, moans, or thoughts indirectly or even blatantly stating he's cumming.
In addition, instead of a blackscreen fade out in the middle of sex and then cutting to post-climax, it would be vastly better to show some form of animation or image of him actually cumming inside or outside in whatever situation he's in.
As of Chapter 6, he has allegedly cum 7-10 times, but not once did we "experience" his climax. We simply saw him doing something, then he's done without any sense of buildup or payoff. Just showing sperm leaking is not enough to get the thrill of the sex event.
Specific example: the park bench after the fair... she sits on him, pulls it out, then... blackscreen and they're done? but acting like both of them climaxed? That's a fake-out and disappointing.
