Horrible.
First off, the texture you place on the sphere representing the Earth displays both American Continents TWICE in one revolution. Obviously you went about the quick way of making a seamless texture for this. It made me first think that you had the planet spinning the wrong way... but in fact, the sun would set in the East for one set of the continents and set in the west for the other set. The stars also jumped around every once in a while, and the animation of the moon was so choppy that it would appear large in the line of vision every so often for 1 frame and then go about its merry way getting small and distant again. Anyway... the last thing i wanted to mention is how hilarious it is that you tried to name this something cool, like "Shattered Worlds", which is actually almost cliche, and even then is still 100 X better than the Flash for which it is the title.
