Orbit - Playing with Gravity is a puzzle game where you have to play with the forces of gravity to send planets into orbit around a black hole. Just tap the screen and drag your finger a bit to outline the orbit for your planets.
The game has more than 40 levels where you have to keep a certain number of planets in orbit. For some levels you have just one black hole around which to orbit, while in others more will appear. With two black holes, for example, your planets usually make an infinity shape.
As you advance you can discover new complications. For example, you'll come across black holes that repel you, or the gravitational pull of other planets that suck you in.
Orbit - Playing with Gravity is an original, fun, and very pretty game. As they follow their orbits, the planets leave a corresponding trail of color, so by the end you'll have created proper works of abstract art.
