Could I make a suggestion, JX?

If its going to be a problem of having people in heaven and have them to be able to find out different polarities and switches too easily, why not make the objects to be shifted neutral?

Rather than shift players, have eight objects, each representing one of the points of a compass, there when the first player reaches heaven. He can shift from the beginning, but with that many objects to shift up there, it would take a while to figure out what goes where.
