Hole Defense

Enemies are coming to capture your castle. You need to protect your people from intruders by using everyhing you have: Digging holes, upgrading and recruiting new soldiers and using your special abilities such as summoning an aircraft, hurling a lava rock, releasing bombs from your balloon bombers and freezing them all. Don't let them capture your castle at all costs!
