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.
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.
