A a small dragon you have one tough task. Defend your father under attack of enemies. You move all round the place and destroy any danger sooner than it gets to the fat dragon. The praxis is about clicking the left button of your mouse until all the things are dead. You can catch them, take them high or throw away. The start is without many defensive alternatives but after every wave you can visit shop and buy some defensive objects. The money is gained by destroying the foes.
