great idea, one suggestion
I know it's experimental, so I'll just leave with one suggestion.
Because it's using perspective to position the camera, sometimes when the objects are reached, it happens near the edge or outside of the "camera," and we're left (or at least me) to wonder what's happening cus we can't see the thing
So I suggest when we're done with the level, the camera will automatically focus on the character, so we can see what's going on.
