The object is to score as many points as possible by shooting as many enemy ships as you can. Use YOUR MOUSE to control the ship (mouse poiter). Do not let your mouse go out of the white box surrounding the screen. If you do it means automatic game over. To shoot an enemy, simply place your cursor somewhere underneath it, and it will fire bullets. You may need several bullets to kill the enemy. As the game progresses your weapon will automatically get more powerful. If you let the enemy drop off the bottom of the screen you will loose 10 health points. If enemy shoots you you will loose 1 helth point. Be sure to collect power-ups and health packs! Good luck!
