From Phaser Tutorials.com: "In Part 1 of this tutorial, we created our Node.js server, set up a basic Phaser game, and set up our server to run Phaser in headless mode, and in Part 2 we started adding in the logic for adding and removing players to our game.
In this tutorial, we are going to add the client side logic for displaying other players in our game, add the logic for handling player input, and add logic for the collectibles players will pick up."
