Yep! Actually this requires me to explain a little bit more about the whole "world" first. Spoiler ahead:
The world is actually just a person's mind, and the person's mental health is slowly going down the drain. The characters inside the brain are all the healthy emotions and concepts that the person is aware of, and they're trying to fight their way through all the negative emotions that keep coming across. Hence entropy being the main plot. All the subplots and side branches are representations of memories - or rather, fragments of memories.
I've started sketching some ideas down, maybe I'll post them tomorrow.
Need to get cracking on learning how to program this thing as well lol
So one person's mind? So that person is plot important and all the characters are people they've met or some of them?
If you're going to script, you might want something like GameMaker or an alternate game design engine.
