No, there would be various things that you could do to add a fourth dimension but what I would probably do a '4d' method which consists of multiple 3d mazes linked together through portals, and to make it even more mindblowing and confusing, the portals would change the end location based on the maze you enter from. I am probably not explaining this very well so I will give you this link: www.astrolog.org/labyrnth/algrithm.htm. This contains a bunch of different maze generating algorithms, click on the 'Higher dimensions' to get an example.
