This game is great, with pick up and play controls, fun puzzles, many collectibles, and its clean. The bad guy, Count Bleck, takes many of his decisions from the Dark Prognosticus, which is practically his bible. The Light Prognosticus is a holy book that guides Merlun, Mario and the gang. Count Bleck also forces Peach to "marry" Bowser, which many parents will think inappropriate, but I don't think so. There is also a few of Count Bleck's minions that use Mind Control, Magic, and Flatulating to stop Mario on his quest for the Pure Hearts.
