Ninja City Defense

Use the Mouse Click to aim and shoot your cannon. You can also hold down the left mouse button to keep shooting, just be careful you don?t run out of stars. Use the Ability Shop to buy one-time use or permanent abilities to help you with your fight. Each city will provide money at the beginning of each round so try to keep them alive. The Numbers or Numpad 1-4 can be used to activate one-time abilities.
