I really don't know yet, I have a story, a finished character, a setting ect. ect. But I don't know what medium I want to go with, maybe I'll make a small side game for em if I ever learn to code :V
Sounds great! Maybe you don't have to code, you could ask someone else? Or you start with an engine, that can be easily used by beginners? Or you make a zine/ comic/ visual novel... you could try out different mediums for your story. I'm sure you'll find something to bring your characters to life!
