Really great writing my dude. Like zero criticisms. Your grammar and sentence structure is impeccable, and like, I wish that wasn't as much of a compliment as it is, but it's the state of the genre I'm afraid lol. I do occasionally wish the MC's anxiety issues played more of a role in the plot, he seems to have a terrible hero complex haha. But I really appreciate that the characters have actual problems. Too many plots from this genre are like, super low stakes? Or their problems are essentially solved with a few dollars and genitalia. Dialogue feels extremely natural, MC isn't a D-bag or a blank slate. I cannot imagine what kind of sick person would actually play without the hamster hints on though, I feel like that could be implemented a bit better? Maybe with a sound cue, or the little guy could glow a bit or something. Idk, but for me it wasn't a particularly enjoyable gameplay element. Also the fact that the beginning leads you to believe it will have elements of investigation where you have to find clues and then piece everything together, only for that element to be dropped entirely, was a bit disappointing. And also made the hamster bit even more strange as it's the only interactive aspect for 90% of the game.
But truly minor issues considering they are essentially bonuses. I feel very attached to the characters and like most of them. I feel like maybe you should stop introducing new characters soon, though? Just a bit overwhelming, there are like 30 characters at this point. I get all excited to learn more about a character and then 5 more characters are introduced with their own unique issues. The MC's life has such an insane amount of attention from so many different people. Maybe that's just me though, idk. Overall, one of the best AVN out there right now, you should definitely be proud of what you've accomplished so far
