Hentai Academy knows exactly what it is, a browser game where you click through dialogue and unlock sex scenes with schoolgirls. No grinding, no puzzles, just straight to the point. The art is that classic hentai style, big eyes, impossible proportions, the works. First girl I went for was this blue haired chick in a sailor uniform, her intro scene had her bent over a desk before I even learned her name. And honestly? That's refreshing. Too many of these games pretend to have deep storylines when we're all just here to see animated titties.
The writing is... look, it's not winning awards. The dialogue reads like it was translated through three different languages then back to English, but somehow that makes it funnier? Like when the redhead says "I am wanting your education stick" I lost it. You can't take this seriously and you shouldn't try. The scenes themselves are decent, couple different positions per character, the animation loops are smooth enough. Though the sound design is just one wet slapping noise on repeat and after the fourth girl it starts to grate. I wish they'd varied it up a bit but whatever.
The July update added new characters apparently but I couldn't tell which ones were new since the whole thing feels like a fever dream anyway. There's this one scene with the student council president where she's supposed to be all authoritative but then immediately folds, classic trope but executed with zero buildup. Still fapped. The game doesn't pretend to be anything else and I respect that, even when the UI looks like it was designed in 2005 and the text sometimes overflows the dialogue boxes. You're not here for polish, you're here to see cartoon schoolgirls get railed. Mission accomplished.
