It's really basic and simple. Circles appear, which gobble up your squares. Try to pop as many circles as you can before all of your squares are gone. That's pretty much it. It's toddler approved, at least!

The requirements for running it are kind of high - I'm not actually sure of an easy way to package an IPA for others to use, but I can try to do a free App Store submission if anyone's interested. Right now, you'll actually need Xcode to build/run the game, so, really, you won't hurt my feelings if that's a bridge too far :)
