Try to defend your castle, bomb all the enemy ships! Dont ever let them come close.
As Always, Good Luck and Have Fun.
Use the mouse to move around and hold left click to shoot. The objective of the game is to destroy all enemy ships and to protect your castle at the same time. There is a cannonball reloader near your castle so you can restock on ammo there. A good strategy would be to just stay near the reloader and keep firing. That way you can release more cannons and finish levels faster. Good Luck!
