Yeah, I think it's usually the writing for me that ticks me off in VNs. I know they're just sex games, but sometimes the lack of character or story depth, or any kind of logic at all makes it feel like it's written by an AI or something, it's just so basic and low-effort fap fantasy junk that always feels really off. It's even more tragic when the renders are really great.
This game ~100% nails the writing, though, and it's probably one of the few games on here where I haven't rolled my eyes every other line. I'd say most of its issues were in chp 1 and look to have been resolved, so other than that it's only really minor things that could be improved, like render hiccups (the Chen girl's glasses sit awkwardly on her face on the post up there ^- for example, there's a Mason render during one of his scenes that looks like he broke his spine, and so on).
As far as VNs go, though, I think way too many authors have focused on the 'visual' part of VN as opposed to the 'novel' part, which is a shame. There's already an endless number of shallow, sexy images and videos out there of REAL women... I don't think simply translating that into polygons is really offering much
