Help a little stick figure man jump across gaps to reach the red flag at the end of each level. Set the angle and the power of the jump with the mouse. There are three main stages with ten levels each, for a total of thirty levels. There might just be a secret stage that you can unlock if you hop well enough! There are other unlockables too, so hop as fast as you can and keep your accuracy tight.
