I knew my awkward phrasing would throw the topic, too... when I say "levels", I'm thinking less of distinct world transitions, and more of abstract mission objectives. It could be interesting to swing a camera around a (properly executed) "3Dish" sprite, where you get the transition from a flat 2D, to the angular view, to the over-the-shoulder (or, hell, even angular) perspective. Again, I hold no delusions that this is not both arduous and potentially game-ruining. The upshot is that, when properly executed, this could also be a must-have feature.
