It's a short linear story, up to where you got, since it's based on triggers and maybe it hasn't worked correctly. Tell me the part and I'll tell you how to get past it
I got to where you get on the train. It showed "The End" on the screen and took me back to the menu, but like I said, "Volume 2" was still locked. Just trying to figure out if I actually got through the full game or if there's another part that didn't unlock properly. Thanks!
