This is a simple multiplayer game where players can move around on the stage (arrow keys) and change color (space bar). Press C to toggle multiplayer connection. If there's nobody else online, try two browser windows at once with this project open, and connect both. You'll see the other version of you moving around! (players may glitch out and spin if they have a poor quality internet connection) If you're interested in how it works, click "See inside"! I've left detailed notes to help you understand what's going on if you want to use this system in your own game.
