Save a little birdie from those evil humans by shooting them down! Fly around using the arrow keys or by moving the mouse, and press the Y key to shoot, if you have a standard keyboard. If you have a QWERTZ keyboard, press Z to shoot. You can also absorb your enemies' blows, and send it back to them by pressing X. This effect only lasts a short amount of time, but is extremely effective in dealing with larger ships. Depending on the level of difficulty you choose, you will have a limited amount of lives. You loose a life each time you get hit and once you lose all your lives, its game over.
