DarkMoon delights in repeated jokes, and Luigi’s difficult relationship with stairs is one of them. It culminates in a sequence at the end of the Haunted Towers mansion: to get to the boss battle Luigi needs to ascend a very long staircase that comprises many flights. Each features three sets of stairs, but only one will allow Luigi passage. If he picks the wrong flight, every step will flip into a sheer slope and he’ll helplessly slide all the way to the bottom. The challenge is to figure out the clues that lead you along the correct path, but even when you know, it’s rigged so that you’re bound to fail several times, and the further up Luigi gets, the further he has to slide down. It’s a joke that quickly gets annoying, then frustrating, but then, through audacity, manages to break through the other side.
