Shoot the aliens before they throw rocks at you.
The default controls for the game use your device's gyroscope. So to play the game you can either stand or sit on a swivel chair with the device held in front of you. You can then turn 360 degrees to see all of the alien's holes surrounding you and when one pops up, aim using the red circle in the center and tap anywhere on the screen to fire.
Alternatively you can change the controls to use a joystick instead so you don't have to move around. With this control option you can use the joystick on the left to look around and the red button on the right to fire the slingshot.
Your highest score will appear on the menu page. How many points can you get?
