Be careful when jumping around the obstacles and regulate your effort according your heart beating.

You are in a ship that needs planet's energy to fly, so you have to jump from an orbit to other in order to avoid running out of hydrogen (blue bar). But be careful, you could dry the planet out of energy (orange bar) and it'll explode. The mouse click is the only control you have.
