PICO8 "Live P8SCII Editor"

this will mean nothing to you if you're not a PICO-8 developer, and it's not even a game, but it is an experiment in creating something usable in <560 characters of code... :)

If you play around with PICO-8 development, as of Feb 2021 you can use P8SCII to encode text with changing colors, borders, size, and positions into one long string in your code. This is an attempt at a basic 'text editor' written in <560 chars that lets you live visualize the effects of common control codes.
