At its simplest, it is a physics-based puzzle game. In Momentum, you transfer the momentum of colored balls to get them into their respective goals. To do so, the player controls the flow of time and transfers all momentum of one "source" ball to a "destination" ball. Various interesting mechanics impede or assist in this goal as well.
