Levels also sometimes feel a little below par, wearing you down with sheer numbers, rather than presenting interesting scenarios. On the plus side, it's a fairer platformer than Lost Levels (which started to get cheap beyond all reason towards the end of the game) and the shorter sizes make the constant need for restarts more palatable. Who knows why it insists on dumping you back to the stage select screen after each death, though: this is minutes and seconds of our life, Nintendo!
The requisite dexterity all but destroys multiplayer, as later stages boast so few safe landing spots that not even four expert players could expect to survive. Nabbit is a cack-handed fix: he can't take damage, but that doesn't solve the lack of screen real-estate problem. It's not entirely clear how his presence helps anyone.
Luigi U does make up for it with an expansive single-player campaign built for replayability, however. The price is on the steep side for DLC, but there's just as much content here as in the original game. More, if you include the hidden piece of Luigi art on each stage, which is presented with such flair that you can't help but seek each one out, despite the lack of tangible reward.
Like its star, then, Luigi U is a confused ball of contradictions, but despite our numerous misgivings it offers a challenge that Mario vets will tackle with green relish.
