As a Rock Rocket, you have to shoot out of a cannon and destroy obstacles in your path. Build your power up before you fire off. You do this by moving your mouse from left to right and vice versa. To let the rocket go, click your mouse. At the start of each level, you have to choose a monster you want to play. Each one is based on an element, so choose one that will do the most damage and help you win the fastest. When you are powering up, you get more power when you move your mouse more.
