It's really quite simple, after the first 10 levels I believe(each section is considered a new level, you can see which level you are on at the bottom left,) it just keeps repeating levels in random order, so once you have all 10 levels down, it's just a matter of doing them over and over again without messing up. This was done at work where I don't even have access to photoshop nor the time to photoshop it, plus I included the whole screen with it(assuming this damn thing will allow the side.) Once I get home I'll try to figure out how to make a movie of it.
