Jump on the hummocks and reach the other end in each level without losing all your lives, to proceed to the next level.
But, itís not that easy to do! Press and Hold Space Bar to set the power of your jump shown by the bar on the left. When you're satisfied by the power level, Release the Space Bar to jump.
Avoid falling into the swamp or you'll lose a life. Also remember that the hummocks will eventually sink in the swamp, so don't stay on them for too long. As the levels go up the difficulty goes on increasing. Good luck!
