This game is all about explosions and timing. It's in Japanese, so you can't read the words, but the gameplay is fun, and it can be quite challenging. Once the balls start floating up in to the sky, they will begin to fall. At some point you'll need to left click the mouse somewhere and begin the Chaos theory. Each time a ball is hit with an explosion, it will produce an explosion of its own. This should cause a chain reaction and if you do it just right, it will eliminate all of the balls. Chaos Theory is addictive, even though you may not be able to read the text in game.
