Foucault
On every level the colored balls are shown. When dragged and released, the ball is moving like Foucault's pendulum. When the balls are colliding they change the color. If they have the same color, they are popping. When all the balls except the one are popped, the level is finished. When the ball is dragged it doesn't affect other balls.The total time of playing is shown at the end of the game.
