I made a PICO-8 multiplayer game for the latest Kajam - https://alakajam.com/multiplayer-kajam/1121/colour-crew/

I made use of the GPIO stuff to send updates to a server so that the three (or more) players can collaborate and together solve the puzzle that is the Colour Crew!

You must have at least 3 players since there are three primary colours and each player can only change the state of one of these colours.

Can you find and sign the Journal of Champions?

PS: the cart is hosted on my own server as I need a modified html wrapper to read and write to the GPIO flags.
