When the game starts, a Start Game page appears with an oval blue button. When touching the button, the game starts, and we see a tank at the bottom and flying airplanes (from two types) at the top. When touching the tank, it fires. We try to fire the airplanes and gain points. A healthy yellow line(tape) appears at the right top. As we gain points, the tape shrinks. When it vanishes, the game is over, and we see the score and the Personal best. If we want to start the game again, we touch the Restart button on the right to. If we want to exit, we touch the exit button in the top left.
