If your character’s appearance have an important role in the story, don’t change it for the sake of optional customization. But if you can manage to do the extra coding and/or your character’s appearance doesn’t really matter in terms of storytelling, you can proceed so with the optional appearance.
I wouldn’t say it’s a BIG part but when i make stories i feel like i’m casting for a movie and like characters to look how u envisioned them, even in multiple versions. I do think I can handle the extra coding for the FIRST episode but i might have difficulty with further on cause i’m still getting used to remembering choices
I suggest you write down the choices you’ve already made in either on a document or a sheet of paper so when you have to remember a choice you created from the first chapter, just look at what you wrote and type it into the coding.
