Ideally, I'd have liked a third-person camera (by which I mean a camera that's always behind the player and pointing in the forward direction, with the mouse turning the die), but I don't know if that runs counter to your intended experience. But I'd say that direct control is only helpful if it's obvious which direction the die will go if I press "W". Otherwise, a better tracking camera would be best.
Essentially, I'd want a camera that allows me to line up runways to the ramps so that I'm not missing it all the time.
