Jumping Jack
In this multiple tiered sidescrolling game, use the left arrow key to make a small jump and the right arrow key to make a big jump as you leap over obstacles, running across the screen. If you do not jump high enough, you will hit the obstacle and lose and life. But also beware of using big jumps when a small one is needed, you may jump the obstacle in your path but wind up colliding with an obstacle above. Timing is key!
