And, last but not least, a concrete ball, super heavy, that can move the hardest elements around but also take a lot of effort to move about, especially to climb.
Your ball also has the ability to morph, and there are three versions of it: one that is made of wood, relatively heavy, capable of moving certain elements of decor around, a ball made of newspaper paper, really thin and lite, so that you can float it on air and get it to fall gently, but incapable of shifting any element in the game. Thus, while in the previous title you could race a marble through all sort of pseudo 3D environments, in Balance you get a ball that you need to control in the most dizzying of landscapes, at great altitudes. Balance is a game that took the ideas of the older title Marble Madness and took it into the modern age.
