You are in a space 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.
Jumping out of the planet's orbit is the only control you have. So you've to plan carefully your tangent in order to get a new orbit of the nearest planet or you'll die by crushing on a planet or flying away without control.
Try it, it's difficult at the beginning but get's easier with practice.
