Surprisingly, although we can type the code in an external editor with auto-save then switch to the pico-8 to run it, it's a better experience to code directly into the tiny pico-8 window and its tiny font.
@Streakmachine Its limitations are its strengths, I mean the console is weak and powerful at the same time, it's really fun to code within such defined and peculiar specs. You can't make a big game, so you have to make a *tight* game. Great concept.
