I apologize if this has been asked already, I have't watched the Q/A sessions for all the episodes.
In the last few episodes we've been developing the scaling for different Z levels and now the fading. Won't the shrinking of the rooms as you move up a level show things outside the room for the brief time before it fades in? As far as I remember the final game design was to have the camera fixed on the rooms and we were only temporarily using the camera that followed the player (please correct me if I'm wrong and this had changed). It would seem like it would be a little weird to show the outside edges of the adjacent rooms just while walking up floors.
Thanks for taking the time to read my question.
