@ SQ: You clearly have multiple faces of the cube showing at a given time based on your position.
Actually, it is not the case if you are talking about one cube element. It is the other tile overlapping with one above. It's like looking through the multiple floors as if they were transparent. The problem is the floor count. It's not crucial problem, just games tend to not do things like this in tile engines.
Indeed, I'm developer in Unity Technologies with graphics and mobile stuff. And of course you are developing games since I was born. Your CS2D remake source code is just amazing.
