Enemies and barbarians can't survive the King's strike. It's his last tower defense hope and strategically building his protection is the game's task. From the highest tower and his own chamber, he shoots arrows and whatever he's got against the invaders, not welcome to his land. Building a castle without an army wasn't smart. Now his treasure and fortress are both under siege and threat. Allocate the blocks in the best possible position, some to defend his territory and others to automatically shoot with cannons, all done with the Mouse, before they can reach the royal rooms and kill the king.
