Okay, just gonna drop this in here for now with only a few notes. I changed the flow from horizontal to vertical for a couple of reasons. For one thing, it's easier to read. More importantly, it's because I'm visualizing a different way to interact with the story. The most popular format is the page-style format. IE reading an IF novel is akin to a physical book. Make choices at the bottom and go to the next page.
To that end, I laid out the flow horizontally.
I'm realizing that I don't want it to mimic reading a book. I want it to mimic reading a website or text messages - flowing upwards from the bottom of the screen. So, this fundamental change to the layout reflect the experience I want to implement. Simple, but effective.
Anyway, here's the Chapter 3 beats. I'm considering either starting to implement Chapter 1 now, and staying two beatsheets ahead, or writing out all beatsheets before actually scripting things out. We'll see.
