From the Wiki:

PICO-8 is a virtual machine and game engine created by Lexaloffle Games. It is a fantasy video game console that mimics the limited audio-visual capabilities of 8-bit systems from the 1980s to encourage creativity and ingenuity in producing games without being overwhelmed with the many possibilities of modern tools and machines. Such limitations also give PICO-8 games a particular look and feel.

Coding on the PICO-8 is accomplished through a Lua-based environment, in which users can create music, sound effects, sprites, maps, and games.

Users are able to export their games as HTML5 web games or upload their creations to Lexaloffle’s official BBS where other users are able to play the games in a web browser, and view the source code. PICO-8 games can also be exported as executable programs, which will run on Windows, macOS, or Linux.

Do you have a favorite game on Pico-8? Have you ever tried to make one yourself? Do you like the idea of a fantasy console?

Do you have any tips?

I just started playing around with it myself, and one thing I like about it is that you can immediately jump to various editors for anything you play on it. It seems like an interesting way to make a small game.
