You're gonna need to learn how to script in Lua first. Here's the website: https://www.lua.org/pil/1.html It has everything you need to know, you will need to learn TICs functions, most stuff in PICO8 should work in this, here's the PICO8 cheat sheet: https://neko250.github.io/pico8-api/ . I learnt most my Lua through LOVE2D, perhaps you should give that a try first?
