The Cannon Shoot Game app challenges you to destroy a multi-piece target before time limit expires.
You aim the target by touching the screen.
The game begins with a 10-second time limit. Each time you hit a target section, three
seconds are added to the time limit, and each time you hit the blocker, two seconds are
subtracted. You win by destroying all targets sections before time runs out. If the timer
reaches zero, you lose.

This game is also compatible to tablets.
