essentially, if the queen grows too big from her starting height, you will lose. You have to whittle her down as well.
So basically, I need to make sure that I don't spend too much on cards? Not sure how I feel about that when I was supposedly twice her height... was I able to challenge her, ever? it didn't seem to allow me when I tried to go to the castle.
Also, guess that means I'll have to start again, wish I didn't have to lose my whole card colletion...
