Each time you hit a spore, you get 50 points. A destroyed alien increases your score by 100 points, as shown here:

When you are in a stardate where aliens emerge from the incubators, mount your best attack. All hits are doubled! If your attack is extremely skillful and you score 500000 points, the score display rolls over and restarts at 000000. Be sure to add both scores together when calculating your total score.
