A logic game based on the 'Marble Madness' clone 'CG Madness'The goal of the game is to clear up the entire field with your ball. You start in a field of your choice (which doesn't make things easier), and whenever you leave a field, it disappears. You can move the ball into the 4 main directions and either roll to the next field or jump over one field. The ball has a specific color and can only enter fields that matches its color, or two-color fields in which the inner color matches. On the two colored boxes the color of the ball changes to the outer color of the field.
