They want a first-person view with the camera posing as the front party leader, dungeon walls, ceiling and floor surrounding your view. Kind of like looking into a shoe box through the one side that is cut out.
I like to call it “tunnel-vision” 
Making it should be fairly easy, use First-Person Template, make the dungeon (plenty of random maze generators out there), the “tricky” part would be making the camera move so-many-steps-at-a-time. Turning is simple, rotate 45 / 90 degrees in the desired direction.
