Tip: In Time Pilot, head in one general direction--whichever feels most natural (up down, left, right, and so on)--spraying a cone of gunfire ahead of you. If some enemies manage to duck in behind you, make a wide turn to circle behind them. Remember, enemies don't have to be pointing at you to shoot you: they can fire from all sides.
Tip: In Road Fighter's second stage, be extra cautious toward the beginning. The road is very narrow and twisty. A good strategy is to use high gear sparingly and then put the pedal to the metal in the second half of the stage.
