Keep clicking on restart to get the first Kadoatie on the right side of the tree.

Be careful not to double click when sending a warf up. The second warf will not have enough power to go up very far and you will lose a life.

You may find that you score higher if you select small under "select size" and low quality under "quality" before starting the game.

Also if the kadotie is not too far from the middle, click right away to set your first warf. Then you aim the stack towards the kadotie. This can save a few seconds instead of waiting to place the first warf under the kadotie.
