Another logic game, where you have to demolish something. You have only limited number of moves. You can move various kinds of balls, which differ by its weight and flexibility. Heavier balls demolish better, however sometimes you need a lighter one to get to unreachable places, because it rebounds. There is a line, under which the highest point of structure must stand after demolition to be successful in it. Think ahead multiple steps, because sometimes you need to complete two things at once and it is hard to do it, when one has already fled.
