Defend Your Castle
Defend Your Castle by waiting for the enemy and getting ready first! You are the commander of your castle, and at your disposal is an invisible hand for picking up the enemy and flinging them mercilessly to their death. Drag them back and release to fling them. It is a good thing you've got that, at least, for the invaders you face are crafty and employ many different types of soldiers in their quest for your castle. Have fun!
