Initial thoughts: too much of "you". Try instead, in the obvious places: "to create your post-apocalyptic stories, most of the players create main characters in the story." "but one player gets to be the opposition ... Basically, everything that opposes the characters."
When the screen splits into the 4 things you do, the navigation gets weird. "Be a protagonist" tends to stream by really fast and land on the last panel. I had to really mess with the forward and back buttons to get it to actually go at a readable rate.
Other than that, cool.
