Asteroid Defense (Bigs)

ALERT! Asteroids have been detected and are suspected to have a direct course to Earth, shoot them all down before they make impact with the city!

Controls: 

Left and Right Arrow keys to move

Space to shoot

(Disclaimer, this is the second game I have made using unity playground, in this attempt i have tried balancing out the spawner with the movement and projectile rate. Hope you enjoy :] )
