you are in control of a happy spaceball to take risks. When the game starts, you can use the arrow keys move the spaceball and press the space bar to jump. You need to help the spaceball pick up all the popcorns for energy and then run into the end zone. When the spaceball is beneath the end zone, you shall press spacebar to pass the level. There are a number of aliens and the enemy spaceships in each level. You shall try to avoid hitting them and dodge the attack from them. Once the spaceball is hit by the enemy, it will lose a life and can not be moved for a while. Pay attention to the energy bar at the top of the screen. Are you ready? Go.
