I just finished this game and I loved it. It's definitely a departure from the other RPGs that takes place in a more medieval fantasy setting. Its nice to actually see an RPG with a more modern, albeit future setting. I'm glad the developers took the time to go all out for this game.
That said, I found some bugs that I thought should be addressed:
During toy robot chase, after you get it for the ferryman, you have to talk to him on his left side. If you try to talk to him from any other side, the game freezes up after dialogue. I guess just talking to his left will fix the issues, but I got frustrated with this until I talked to the ferryman on his left.
During the Haruka thief mission, if you defeat the thief boss and then try to go back up north, the battle with the thief boss will happen all over again, even though they've been beaten. I was surprised when I suddenly found myself the thief boss again, even though he was defeated.
Of course this could probably be the version I installed during the time, so who knows?
