There's some hot scenes, no glaring grammar/spelling issues but I'm reaching for positives here.
The problem isn't that its AI art, its that the proportions of some characters are exaggerated and pornified to an absurd level, the characters themselves are just taken from other sources, Makima and Saitama being the ones I know for sure, and their smiles look like they are possessed by Satan himself.
The writing is painfully predictable, every girl is either a complete slut already or has 0 issues becoming one, the conversations between MC and his girlfriend can all be summarized as "hey I'm a complete slut!" "omg you're such a slut, damn you love teasing me." I found myself just skipping most dialogue by a third of the way through.
tl;dr If you want cliche art to click through in this style/genre, go for it. If you're expecting a decent narrative and characters, which I'd expect from a VN with 0 player input, look elsewhere.
