*sniff sniff* You smell that? Sounds like an up and coming voice actor. Anyways,
For the process, I typically begin by planning the murder before anything. Then, I write daily life based around the murder, planning the events that lead up to it so everything can be tied together in a neat little bow. I do wanna note, for any fangan creators: Daily Life is AS, if not MORE important than Deadly Life, without it, your deaths and plot twists (Which true colors is full of) will make no impact. Have your characters be human and talk.
After that, I do revisions with a different team, I do little scenarios and write short interactions before going into daily life writing to make sure I'm not rusty with the characterization of anyone in the cast that's still alive.
Then for trials, that's a whole other can of worms. I already plan ahead minigames and truth bullets in the investigation doc, so there's no hassle with those.
Culprit Breakdowns are written ahead of time, most of the time. It ends up just being like a puzzle, with me piecing each and every little plot piece and important moment together.
Then, closing arguments, post trial, dream theater, foreshadowing in last moments of the chapter, suspect gabby, yada yada.
Then after that, I hand important lines over to my amazing, wonderful, increeeeeddibly talented, occasionally underrated, and perfect voice actors. I can NOT emphasize this enough: True Colors would NOT be as good as it is now without the voice actors, you'll see, Max. Wink.
As for the chapter that was more difficult to write, well, chapter 5 is kicking my ass, but I suffer for y'all <3
But for already written chapters, the most difficult to write for was either chapter 3 or 4, for my own little silly reasons.
Anywho, the asker of this question gives me a good segway into next post.
