Tap your spaceship carefully through asteroid fields, space mines and laser barriers, always keeping an eye on your fuel and planetary gravitation. Different collectable power ups can help you, but mastering the challenges and crossing the fields requires your pilot skills and understanding of gravity.
Be careful not to hit an obstacle or crash into a planet or you'll have to start again.
Collect stars to buy better ships and collect fuel barrels so you don't run out of fuel on your mission !
