The rooftops are generally too high for her to jump to, even with Doubleflight working here. That seems more like something Ven would rather do.

She turns at the sound of the familiar voice, glad to see Nida again. "The village did have that to its advantage. Even if we were pulled to some seemingly-random location, at least the general locations didn't change. We could still get back to where we wanted to be with relative ease. Here... everything seems to change. There are only a few places that don't seem to move around, but I can't tell if that's really true or if I keep getting turned around every time I try to look."
