Time, Space... AND LASERS!

When you were flying throw SPACE PIROTS GALXY OR STUFF(TM), SPACE PIROTS(TM) shoot you're engine.  You stoped at the asteroid field, when they're turn on the BARIER(TM).  In order to surwive, you have to move. To move, release fuel from broken ENGINE(TM), or shoot you're LASER GUN(TM). How long will you surwiwe, before PIROTS(TM), ASTEROIDS(TM), ALIENS(TM) and other SPACE STUFF(TM) Will Get You?
