Well, almost everything. The mechanics of the game are still the same but after a few months of agony and careful consideration I am proud to say that I have found a style for the game that I can draw by hand without the insecurity that involved working in 3D. That un-comfort zone needs to be revisited at a later point in time.
Below is a screenshot of the game how it currently looks in Unity. There are some placeholders at work but the background gives a good impression of where everything is heading currently.
