Thangs and level Art for 2.5d view


#1

So I was looking at one of the latest levels and realized that some objects seem to be drawn to show with a vertical perspective and others are drawn at an angle.

As depicted in the diagram below we have boxes on the vertical and the cart on a diagonal 2.5d type of setup. What were the thoughts one these when they were being designed and is there an advantage of one over the other?
