In our solar system, orbiting the sun, the planets rotate. Imagine that you can control the orbit of their displacement. This in the game Save The Planet and you will. Around the sun will rotate our planet. In her direction from the expanses of space will fly huge blocks of stone. If they collide with the planet, it will explode and break into pieces. To protect her from collision with stones, you will move the sun. Shifting it you will change the motion of the planet. So be careful and try to plan your moves well in advance.
