I've been cleanin' up some character code the past 2 days. A lil' bit in the afternoon, I decided to take a break on that and see if I could have the potential to add official modding support.
This is so far what I've got. I made GameMaker read folders off the "mods" directory the game comes with and some files like a metadata.json and a mod icon. Also got a mod list.
I'm gonna keep it goin' and see how far I can take this.
