The upper-left area is actually 15 sprite variables; and it goes through roughly 20-25 pictures to make it look like you are wandering through a maze. I did this because 25 picture graphics is more appealing than 1 for each direction in each 'square' of the maze.
The idea behind this setup was to look similar to an old NES or DOS system first person RPG. Since I have those 15 variables, If I want, I could actually use any graphics for the walls, so long as they fit the size of the image I originally set for that portion of the wall.
That being said, If i could find a graphical artist who would love to draw walls, stairs, etc, I could actually make the labyrinth 'window' itself look better with 24-bit colors. I, however, haven't this talent.
Everything you see is graphics. Now, the text is in a window with 0 opacity.
