Diaballic has you controlling a ball, trying to constantly go forward in a world that's constantly trying to leave him behind. He's just trying to keep on going and going, collecting points and gems, and trying to avoid falling to his death, or getting blown up, or disintegrated by lasers. All he can really do to avoid his fate is move left or right, and double jump to avoid danger. He can also jump off screen, and have his position be indicated by an arrow showing where he is in the unseen top of the screen area. And in the newest update, he can also pick up powerups to disable the dangers in his way or to draw in nearby gems, or to temporarily have lighter gravity. He can do so little in the face of so much. And the ball may be a she. It's never really indicated.
