Just purchased-- the story drove me crazy for the longest time with the girl controlling the watch!!! I downloaded chapter 14; which one of my save files should I use. I have the broken watch version and those saves.
So the new content of this release is Episode 14, which all takes place after the gym scene in Episode 13 as long as you don't play the broken watch branch, which should now be possible to choose between the routes regardless on the path you're on.
