S.O.S(Spaceship Out of Supplies)

You're a spaceship pilot who forgot to pick enough supplies for the intergalactic flight. You noticed it a couple galaxies ago! You need to plan every move in an efficient way, so you not waste your spaceship's power, cause EVERYTHING costs power. In each galaxy, look for a warp: a blue portal that connects galaxies. Your spaceship navigation system will point the nearest warp position with an arrow near your spaceship. You can move the obstacles to reach to the warp with shooting but BEWARE, a collision with an asteroid will cause the spaceship to rise it's shields, wich is very power-expensive!
