Just a quick update before the day is technically over here - my murder board outline of sticky notes is progressing, and I'll definitely have to decide on which ideas are essential and which aren't, but at the very least the major plot threads are starting to come together, and I think I have successfully managed to limit myself to 3 endings (and maaaaybe one "hidden" ending, if i have the time), so yay! For now, bedtime, but tomorrow I'll be hashing out those essentials vs non essentials! Maybe when I'm done I'll post a photo of my mess so that the evidence of my very shakey organizational skills are saved for posterity :P
(Side note on that: I did start looking into some of those websites that can do branching web / flow chart type things, but there were too many options and I started to slip into "procrastinate by over-focusing on unimportant details" mode, so I decided to go old school and break out my colored sticky notes. That being said, if anyone has recommendations for sites that are easy to use, I would definitely love to check them out and would appreciate any words of wisdom anyone has to offer!!)
