Marble Madness — About this game
Guide one marble through six obstacle courses viewed from an isometric angle. Slopes and narrow paths demand small corrections, while hostile creatures and awkward barriers make each route harder to follow. Watch the approaching turns rather than steering only at the last moment. The challenge is to keep the marble on its route and reach the end of each increasingly intricate course.
