Asteroids
Destroy as many asteroids as you can while not letting them hit you.
Control the orientation of the spaceship by turning the card:
if holding it in front of the webcam. (tags 6, 7, 8, 9)
if you're playing on a desk with the webcam tilted down (tags 10, 11, 12, 13).
Flip the card to switch between Black and White modes.
Asteroids of any color can hit you.
Your shots will only hit asteroids of the same color.
Reset the game by showing the reset card. (tag 2)
