Help your ship escape the gravitational field obstacle course in Gravity Thruster.

Before taking your rocket out into space, learn to control it in the obstacle course which is Gravity Thruster. You'll be flying in a gravitational field, so you have to thrust with one hand and steer with the other. Learn to use the tractor beam to carry orbs along with you, so you can move them to their goals to unlock the exit portal and fly out of each level.
Watch out for blocks and other obstacles, don't hit the floor and beware of the auto-aiming gun turrets. Don't forget you can shoot back at the guns and obstacles you wish to to remove. To unlock the next level, complete the tasks and get your rocket to the portal without incurring too much damage.
