Jose "JR" Rodriguez is giving a talk at the Spotlight Web Games conference entitled "Phaser.js: The swiss army knife of web games":
"With several years of development under its belt and hundreds of contributors, the Phaser.JS framework offers a variety of time-saving, game-specific constructs as well as over 700 individual code samples and solid documentation. A fast, free, open source framework for creating web games, Phaser uses both HTML Canvas and WebGL.
Some of the built-ins include: states, a number of physics engines, sprite sheet/texture atlas support, world and camera objects, tiling, particle systems, debugging helpers and a lot more. The Phaser community has also written some super helpful plug-ins for example Spriter and Spine integration.
This all means that you can focus on the things that make your game unique without having to worry about the basics.
As someone who had spent years building up a library of ActionScript game code, JR appreciates what the folks at Photon Storm and the open source community have done and continue to do with Phaser."
