The King has sent out a notice to all of the kingdom saying that any knight that wants to win the princess' heart may do so if they pass one simple test. You will issue that test by building towers on the open field to destroy the knights as they make a dash for the throne to swoon the princess'. Click and hold your mouse and slide left or right to select a slow tower or an attacking tower. Collect the coins, potions and scrolls that drop from the knights that you destroy. These scrolls will give you special towers to build and the potions will restore the health of all your towers.
