A games I learned to love to hate or is it hate to love? Anyway, I was able to raise my score by shooting ahead of the "targets". Also use burst of rapid fire with short rest, so as to not overheat. cannons. Their is a point system for the targets, if you read the intro instructions. If I remember, the small blue satellite disks gave you the most points. Other than that, practice, practice, and more practice. The game is free after all, once you buy Aurora Island Personal Space or even better yet... use a friend's space.
Hope this helps,
