So I’ve played through CoTN a few times, I’m trying to join Kaoru but every time I get to the point where we leave after stabbing the crap out of your friends, the story goes on like it didn’t happen. The game’s been around a while, so I guess this was just never fixed or did the author just have ADD?
Sounds like it might be broken. I can’t remember the game well enough to know at what point that occurs and it’s one of the games I don’t own so I can’t double-check. Send an email to the choice of games support email address though and they should be able to help you. If it is indeed a bug they’ll patch the game to fix it.
