Grade: C- (70.97)
Your mission is to fly around the galaxy picking up solar energy cells. Pilor your ship over the cells to pick them up, but avoid the fireballs, fired from sentinels, which move back and forth on the periphery. The fire button controls your speed. If you pick up all of the cells before time runs out, you'll skip the next matrix, earning all of the points from it. After every 5th screen cleared, you'l move to a challenge round, in which you get bonus points if you clear the screen before time runs out.
