This game was a huge insult to the first game.
They took everything from the first game and made it worse in every way possible.

The most frustrating part is what they did to the characters and the plot. The plot was terrible.
It doesn't even have a clear antagonist until the last
couple chapters. The characters were absolutely butchered, for example Tae, who has a new appearance/model, new personality, and even calls herself a different name for... some reason?

Tae was a pretty decent character in the first game, whereas here she's just another "hehe who is your favourite girl hehe" trope. They even added a hotspring scene where she's naked. (nothing visible at least) That scene takes place during a random part at the end where she randomly starts complaining about how women are treated (which she never complained about outside of this one scene by the way) before and after that scene starts, which made me feel like they were making women's rights into a joke.
Gouto was butchered as well, just showing up to say "Oh hi I'll add this to your notebook" at the end of every cutscene.

Overall the gameplay is just a downgrade, story was boring to the point where I just skipped dialogue since everything was very predictable, or just recapping events that have already happened.

This review is a massive rant with no structure, so I'll complain about another scene in the game.
At one point, there's a massive plot dump, but the game doesn't respect your intelligence and asks you if you need to rehear what was said every 5 messages. It was actually insane, and very annoying.

Anyways, I'll end this here, I've played bad megaten games and hated them before, but none have disappointed me until now.
