Move the Earth around with the power of your mouse to dodge the waves of asteroids attracted to you by gravity. Get them in a close orbit to destroy them or pick up a Gravity Blast and shoot them out to space. The Earth will explode after 3 hits from anything so watch out!
Use the mouse to move the earth around. Get asteroids to orbit you in order to lock on and destroy them. You must pick up items in a similar fasion (lock on and capture them not run into them!). For detailed instructions it is recommended that you view the in-game directions.
