Aim of this game is to get to the bottom and find the blue magic diamond. It is said that the one that finds it will grow 2 inches taller.
Control Nanny by moving your mouse left and right. Get to the end of each space rock, then click to make him jump using the power meter, move your mouse up and down while you click to change the power of his jump. Press "cancel" if you changed your mind. Hint: If the next rock is right below you just double click on that rock and Nanny will jump there without the power meter.
