Ninja Dogs is a fun Angry Birds-style arcade shooter in which you'll have to help ninja dogs defeat cats in fortifications. To get started, press "Play" and "Skip" to skip dialogs. Choose the first level in the list and see the instructions, then click on the box to skip. Use "AD" to move the map to see where the enemy's fortifications are. Use "S" to scale the map. Hold down the left mouse button and drag to the side to aim at the target. Release the mouse to launch the dog from the cannon. To complete the level, you need to destroy all the cats.
