I love PICO-8 too. There are so many games, and they’re all free to play, with the source code available to explore or modify. Games are also reltively easily published online. Some PICO-8 games are genuine works of art. I’m always impressed by how creative people become when working within tight constraints. I wish I’d had something like this when I was a kid. I always recommend Pico-8 to like minded folks, sometimes kids.
