Max number of high goals?

[dmorewood]

The way I read it is that you can continue to score boulders in either the high or low goals but you can't give the tower negative damage. So lets say you shoot 10 boulders into the castle, this means the towers defenses are at 0 not -2. But if you get a technical foul (even if you've scored 10 boulders) then the towers defenses go back to 1.
