For the client, Phaser is included in the code (js/phaser.min.js). You will need npm to install the Node.js packages required for the server. To run the server, you'll need to have Node.js installed.
Clone the repository. Inside the newly created directory, run npm install to install the Node.js packages listed in package.json. Then run node app.js to start the server. The server will listen to connections on port 3000; you can change that behaviour by editing the code. You can access the app by navigating to http://localhost:3000/.
