Try to score the most points in this alien fighting game. Whenever a spaceship appears on screen, it may or may not have an alien. Shooting a spaceship CORRECTLY, BEFORE an alien has been shown is worth 400 points. If you shoot a spaceship WRONGLY, you lose 200 points. If you shoot an alien, that has already appeared, you gain 100 points. Press spacebar to shoot. For each treatment, how many points did you earn? Did you discover the rules governing each treatment?
