Try pressing shift when you sit down, that's the leapfrog.

level 3 u jump then u push shift and u only use arrow keys good luck

To leapfrog, sit down and press shift to leave a sitting friend. Then, send a running friend at him to make the running one do a leapfrog.

When falling, leaving a friend will make your friend jump and go a bit further, helpful for one or two levels.

When jumping, your friend will jump and go a bit higher than you, which ever way you jump or face whilst jumping is the way your friend will go.
