Dev Peeps,
I am not sure if you are willing to answer this or not(perfectly cool if you are not) but I have been playing around with Unity development lately, mostly just poking and developing a mechanic at a time with wide open goals. I had remembered once you talking about switching over from game maker because Unity is much more robust, but I also remember you talking about the challenges with it being a 3D engine and getting the camera to do you want you.
Is this game utilizing the GUI with layers entirely? Or are there sprites/textures on 3D surfaces? I ask purely out curiosity at various approaches that can be taken with the engine..
