You do not. You need to get her down low enough to leave. and then hit the minimum height (which is 1300 iirc in the demo)
and then you win.
For most, around 500 or so. As there is no further stages after that.
What do you mean by get her down low enough to leave? Do you mean height wise and if so what height?
if you bring her below 150, a small scene will out and she will leave. Then you can fight for the throne.
