It's letting go of notions of what makes good code. I had a Moment like that doing Pico-8, since you can only fit 40 or so characters on screen, all the tutorials just use dirty, single or two letter variable names, and since everything is small and you learn a few neat tricks about variables (velocity, coordinates, the mod operator), the code can be really compact... and filthy. It's great.
