Astronauts have it hard enough without the fear of aliens. But, there are aliens among us and now they are attacking the astronauts. Fortunately for the astronauts, the aliens do not like balls that are of the same color as them, so using the number 1, 2, or 3; you can switch the color of the balls you're shooting at the aliens. Use the mouse to aim and the left mouse button to fire the ball in to the mouths of the aliens. Do it as quickly as possible and with the fewest amount of shots possible.
