Finally get to go through this after a while, and unfortunately, I didn't enjoy it.
The mechanics are actually somewhat ok but it's other parts that I mainly have issues with.
Sosuke never grew on me so I really didn't enjoy the romance stuff between him and Ai, just feels forced to me. Some people may enjoy it so i was hoping it would be a optional thing like your other game, but it isn't. And it also seems like he is in some demon subplot but that never went anywhere.
Also, I disliked the love triangle plot, I knew this is for character development but it just feels way too disconnected, don't know why you have to include Kira like this that feels unnecessary, and I don't like how the issue with the demon girl is never acknowledged or developed more, and they just act like nothing more has ever happened.
Yeah I don't like this game but seems like plenty of others do so to each their own.
