Use the D-Pad to steer your jet to avoid the flashy bullet thingies.

Press B to fire at enemies. Collect Powerups (the “P” things that fly around) to strengthen your firepower.

Press A to launch a big missile that blows up lots of stuff. It also makes you invulnerable for a short period. You will start with 2 of these with each life. The “B” pickups will supply you with an extra missile.

If you touch a bullet then you will explode and lose a life! If you have no more extra lives, (shown in top-left/right corner) the game will end. You may continue from the beginning of the level (but you lose your score).
