"The gameplay is simple. You are a planet wandering through a two dimensional universe filled with other planets. Most planets just follow their orbit patterns, but for some unexplained reason you have the ability to control gravity's effect on you. There's a button to activate regular gravity, and a button to activate anti-gravity. As you wander you'll have to use these strategically to control your movement. Unlike most games, there are no buttons for moving an exact direction. The gravity physics are completely dependent on how large and far away your neighbors are. The game would be stupidly easy if you could just walk over to the goal, so this challenging mode of travel is what really makes the game."
