Wait until wind speed hits 9 before dropping the Kass. Hit it just as the head comes inline with your head. Hold mouse button down until the Kass starts to fall. Then on each bounce, tap the mouse button. Using this method, it will only take you a few tries to unlock all of the levels. Just a note to add; when your in the negative wind speed numbers and don't want to wait for it to go back up, drop the Kass but don't hit it. This will reset the wind speed and besides your not sending the score anyway. Also you can make the Turtum walk faster by clicking on the mouse button once.
