/* 
***Disclaimer - MUSIC ADDED AFTER DEADLINE***

With this game I wanted to do something a little different. I wanted to build
my own gamefrom scratcth rather than using your world as a framework. 

I am very much looking forward to implementing AI into this world. Although the 
time constraints wont allow it for this deadline, I will use the same method as
with my election world, and havethe agent detect 2 spaces ahead, if they are 
rocks, he will move left or right, based on his currentposition in relation to 
the sun. 

As well as the new structure, i wanted to write a world that would give me the 
opportunity to showcasecollision detection and mouse controlled agents. 
This is the world I look forward to working on the most, both with and without 
AI.

The game also allowed me to implement a scailing difficulty level which I could 
not with the first.

Rules: 
Very simple. Collect the sun nodes while avoiding the astroids. 
Every 5 scores difficulty increases.
