I think that Dust Hill was completed entirely
Again, later in the interview:
Desert was dust hill. I donít remember the rest.
That seems to confirm the connection, unless she was talking about another desert level, unrelated to the mock-up we have. (She didn't see the picture, it seems. "Youíll have to send me the image so I can see it.") Or, she's on crack.
Probably a bad time to bring this topic up (ICEknight is gonna explode), but it needs to be clarified.
EDIT: Normally I'd search on forums (e.g. A51) when it happened, but they've all vanished as you all know.
