Nintendo-Okie.com writes in one section, "In the first game you unlocked Luigi after finding all 121 stars. Now he’ll be wandering around the galaxy and will be waiting at the start of numerous levels. He’s helping you in your quest to recover all the power stars and if he’s waiting there you have the option to take control of Luigi for a level. He’s not available on every level, but he’s in enough that Luigi fans won’t be kept waiting long. He also feels just different enough from Mario to make the game interesting. His jump feels a little higher and he takes just a split second longer to stop than his brother does. As a huge fan of Luigi I’m glad he has more of a role early on in this game."
