/**
 * Humphrey The Rabbit - In glorious WebGL Form
 *
 * tl;dr A game where you play as a Rabbit who must avoid Foxes and Boxes.
 *
 * History that is only of significance to the author:
 * Humphrey The Rabbit was originally written using pygame (Python 2.7) in 2012 whilst attempting to improve my Python after years of trying to ignore its existance.
 * Now I am attempting to improve my JavaScript after years of trying to ignore its existance, so its time to reinvent some wheels and rewrite Humphrey The Rabbit.
 * One day it'll probably get rewritten in C++ where it belongs.
 *
 * Credits:
 * Sprites are from Biots.
 * Jeremy Hughes sang to the theme3 music
 * David Gow came up with some of the advertisments
 *
 * Sam Moore, 2014
 *
 * Update: July 14th - Well this project seems to keep escalating...
