Fast Ball Catcher

By using the device's motion sensor to
detect the angle at which the phone is held.

Swing the phone which held in portrait mode
to change the angle, and then the catcher
(spinning circle) will move
clockwisely/counter-clockwisely.

Use the catcher to catch those incoming fast balls
which are spawned from random positions and
toward the player's position with speed from
30km/h to 160km/h.

Speed of the balls are getting higher and higher
when the player catches the balls continously.

The more combos player got,
the higher speed of balls will have.
The more accuracy player catch the balls,
the higher score player will get.

Have fun.
