In this game, you hold your smartphone flat and tilt it to roll one ball, while simultaneously using the on-screen joystick to control another ball and keep dodging approaching walls.
If the ball hits the edge of the screen, you're out.
If two balls collide with each other, you're out.
The wall gets longer and longer and approaches faster and faster.
The number of walls you avoid is your score.
(You will get points if the wall disappears completely below the screen.)
You cannot play this game on devices that do not have a tilt sensor.
Depending on the model and type of tilt sensor installed, the ball may not move smoothly.
