+* Phaser is a fun, free and fast 2D game framework for making HTML5 games
+* for desktop and mobile web browsers, supporting Canvas and WebGL rendering.
+*
+* Phaser uses Pixi.js for rendering, created by Mat Groves http://matgroves.com @Doormat23
+* Phaser uses p2.js for full-body physics, created by Stefan Hedman https://github.com/schteppe/p2.js @schteppe
+* Phaser contains a port of N+ Physics, converted by Richard Davey, original by http://www.metanetsoftware.com
+*
+* Many thanks to Adam Saltsman (@ADAMATOMIC) for releasing Flixel, from which both Phaser
+* and my love of framework development originate.
+*
