"Gravity Rules" is a single player side scroller, similar to Super Mario Bros. The player is required to progress through the level, collect items and kill or avoid enemies before finishing the level. The game differs in that the items collected will fuel special abilities. The player will be able to control gravity of themselves and other select objects and enemies. Gravity control will manifest by left clicking a direction, which will bind the selected object's mass in that direction, creating a new "down" and causing it to fall that way.
Multiple bindings can be made, meaning that if something was bound upwards and to the right, it would move towards the top right. Players can choose how much "fuel" they want to put into the binding, meaning that an object will eventually fall as its original gravity re-asserts itself. If a player uses this ability on themselves, their fuel will constantly drain until the ability is cancelled.
Players can change how much mass should be bound using the mouse wheel. Binding half of an objects mass upward would create weightlessness.
