Hint: Flying through the asteroids:
Hold Down/Left or Down/Right and remain in those corners to pass through the asteroids with less damage.

Hint: Finding shields:
Search the slug and wamprat caves on Tatooine to find shields.

Hint: Game over music:
The music at the game over screen is the same music from the first area of the Game Boy version of The Empire Strikes Back (Luke and the Probe).

Hint: Restore energy:
Talk to Obi Wan after he joins the party to heal. Note: This may only be done a limited number of times.
