Which wall/camera was a problem? To my knowledge, I fixed all of those. Actually, there's one angle in level 1 where the camera will move into a wall, but that is because I have collision detection disabled on that particular orbit camera. I haven't completely resolved that section.

As for how I will handle enemies..you're right..that is one of the trouble areas of these types of games. I am going to implement some kind of lock on system and the camera will change to a more standard 3rd person camera in these situations. Kind of like a Zelda lock on. I already have the code that will achieve this(the lock on), but have yet to apply it. This will come much later, most likely.
