The story of the game - you need to get to another planet in order to colonize it and establish a colony there, thereby pushing humanity to space communications - this, in turn, will develop the outer space of humanity!
You are a great strategist - predictor - designer - engineer - HUMAN! - mathematician. You need to correctly build the orbit to achieve this goal: POPULATION OF THE PLANETS WITH HUMANS! OO yeah sounds cool, is it really easy to build a correct orbit? Try this game! Yes, the game is not ideal, but it will show you how it's all done and with what difficulty. This game has ideal conditions, only the physics of the planets works (highlighted).
Good luck in your endeavors!
