Pilot your spaceship from planet to planet, anointing the inhabitants with the good word, use the mouse to aim the spaceship & the mouse button to launch, once you launch the ship you have no further control over it until it either lands on a planet or crashes into the sun, if you get bored, you can use the mouse wheel to speedup the passage of time. The aim is to visit all the planets in the current Solar System before your time runs out.
Use the planets/moons/stars to change your spaceships speed,trajectory.
SpaceBar = selfdestruct Spaceship, (Incurs a time penalty.) Twice = return to original planet Escape = Menu
Disclaimer - Dont use as a guide in how to pilot a space ve-hi-cle, as in the interests of gameplay the physics are not 100% accurate.
