Blastball

In Blastball, smiley-faced balls of different colors are floating over a hilly field, and your goal is to blast them all to smithereens. After a couple of easy levels to learn the controls, this goes from being a task of senseless destruction to a fun puzzle because you are given a maximum number of clicks in which to complete it. When one ball bursts into pieces, those pieces fly into other balls and blast them. Figure out which ball to blow up first in order to trigger a domino-effect series of explosions that will reach all the balls. Red balls blow up in one hit, but balls of other colors have to be hit multiple times.
