Trying to explain how shatter works is not easy. The best thing I can say about shatter is that it constantly changes things up. First off, the music is superb. The music alone is worth $8 bucks in my mind. The game has you play vertically, then horizontally, and then in a circle for which you move in the bottom third. Every world has a boss battle which are really enjoyable and a bonus level. I think I was looking forward to the bonus level every world because the balls start moving really fast and present a really cool challenge. I found myself going to shatter for a "quickie" when I wasn't feeling like undertaking a serious play session. That alone is why I recommend it. It reminds me of how I felt when Super Stardust came out. It kind of took me by surprise and gave me a great reason to go to my PS3 instead of 360.
