This is one example of the problem having too many characters. The MC has to train with Hinata and Hanabi. Both are Hyuga, both tech you taijutsu, both have big boobs, both have an animation of a titjob. The scenes with them talking and training you makes sense, but why both? I think it could have been developed other characters insteed of Hanabi, like Wasabi.
Also, the training is too focused in Taijutsu. You can train Taijutsu in the morning, afternoon and night, but you can only train Ninjutsu and Genjutsu in the morning. Ok, the game is not focused in figthing, but Sarada could teach you at night, because Sakura is there too.
And Anko have events... Why? she barely appears in the story. Kauri, Moegi, Karin, Yodo, Hako and Yuina only appears when you trigger their events, why you can interact with Anko?
Don't ger me wrong, I still love this game. These are just things that could be improved
