The goblin is trying to crush any all the buildings and knights with it’s catapult. Try to aim your catapult right to bring down all the towers with minimun posible shots.
Timing is everything in this physics based game. If you like Angry Birds, you should definately give a shot on this cool game.
Click to start the catapult. Click again to release the shot. If the angle is right, the rock will do the rest.
Try not to waste your shots because you’ll only have a few shots on each level.
