Awesome Art: The new backgrounds, cutscenes and Monika's casual outfit. They're so well done and mesh so well with the game's art, you'd think they were unused assets from the original game.
Memetic Mutation: KONO DADSUKI DA!Explanation Natsuki's dad looks so much like Dio Brando that the Jojo references wrote themselves. These include, but are not limited to: "Natsuki is a Joestar" (due to the modern setting and the fact Dio only had kids after his Grand Theft Me of Jonathan Joestar), Natsuki's Stand being a Memetic Loser (since Dio is a Stand User-and, in fact, his Stand is one of the most known because of Dio's status as a Fountain of Memes-his children also have to be Stand Users, and Natsuki's Stand did nothing to stop Monika from tampering with Natsuki's file), and, as a followup to that, that Monika herself is a Stand User, with her Stand's ability being to alter video games and to gaslight other Stands.
Signature Scene: The confrontation with Natsuki's dad is easily the most memorable part from this mod, in no small part thanks to Natsuki's dad literally being Dio Brando wearing a pink wig. No, really.
mixed with, of all things, "You Reposted in the Wrong Neighborhood"
