They thought dragons were a myth of long ago. They were wrong! One dragon remains, the species' last hope. Use either the WASD or arrow keys to move around, and click to shoot fireballs. You can scroll through the different fireball types either by pressing Spacebar, or by rolling the mouse wheel. The dragon nest is your safe place, where you can recharge your endurance bar, and create new fireballs. To create the fireballs, collect sulfur and helium from the nearby fountains, and return to your nest. In each level, you must achieve a goal of killing a certain number of enemies.
