Pure Nintendo: "New Super Luigi U is not simply a few new levels like Nintendo’s previous DLC packs for New Super Mario Bros. 2. The game features more than 80 new levels for players to explore as Mario’s lanky brother, Luigi. The world map is largely unchanged from New Super Mario Bros. U but each level is very unique. One of the new twists in New Super Luigi U is the 100 second time limit. This smaller window of time means levels are a little shorter than those in New Super Mario Bros. U. The star coins in each level are also easier to locate but are not necessarily easier to obtain. The first few worlds I was able to retrieve every star coin as I progressed. However, the later worlds are more challenging and star coins aren’t as easy to get on the first play-through."
