Sounds like a good plan. It's probably best to put a limit on the branches and not risk the story becoming too diffuse.Implementing a Maximum Branch rule for DOOMED, just to try and keep things reasonable. The introduction chapter will max out at 10 branches, and subsidiary chapters will max out at 5 branches each.
I can always go back and change that, but at the moment there are 319 chapters to be written, so it's probably for the best to cap new branches slightly.
I think you're doing fine!Still struggling to get back into the swing of things.
