}~How to Play~{ Click and hold to aim and release to throw a ball; you will move in the opposite direction of the ball. The goal is to reach the asteroid with the red flag before your oxygen tanks run out. Make sure to watch the speedometers on the side—if they get into the red, you will explode when you hit an asteroid. Red asteroids cause you to explode at any speed. }~Physics~{ The movement of your character is based around Newton's 3rd law, which states that for every action, there is an equal and opposite reaction. This means that when the character throws the ball, it will exert the same force that it was thrown with on the character.
