When I started to play around with the Phaser API, I wanted to tackle the challenge of creating a realtime game with multiple players. I decided to use the PubNub multiplayer framework for the realtime functionality and it worked extremely well. I put my entire project up on Github and you can try it out by clicking HERE (open up two browser windows to test real time functionality). PubNub provided me with low latency with message delivery happening in less than 250ms and Phaser is super lightweight which allows it to work in mobile browser and even on low end computers. The entire project took me a few weeks to develop but most of that was just optimizing the game to send the least amount of messages possible. I wrote a step by step tutorial if you want to try to make this yourself in Phaser, you can checkout the tutorial HERE.
