It will be a 3D environment. The player is a laser turret sitting in a hot air balloon hanging at a fixed position in a sky. The orientation and direction of turret depends on the movement of phone. The player can move the turret in any direction around him (360 degree on x-y axis or 180 degree on z axis).

Below, the sky is all covered with clouds. And helium balloons are emerging through the clouds and coming upwards. There are dynamites tied below each balloon. And if the balloon strikes the airship, the dynamite blasts and the health of the spaceship decreases.
The player has to shoot the balloon in mid-air with his laser turret so that the dynamite falls off into the clouds. There is a button for shooting. The laser will shoot continuously as the button is pressed. The player can move his phone around to aim in various directions while the button is pressed. However, the laser power depletes during the laser is being shot and is not regenerates. In order to gain more power, the player has is to do this: There is a magic gold mirror on the ship. The player has to aim it and shoot in order to regenerate his turret's power.
As the more balloons he bursts, the more points he gets. With time, the rate of number of balloons coming upwards increases and each balloon points also increase. When the airships health reduces to zero, the player looses and his new highest score is set.
