Admittedly, the DS version of Mini Ninjas does have its flaws. Its controls aren't seamless, especially when it comes to wall-jumping, and it's a much more straightforward, action-oriented title than the other Mini Ninjas games. But it also manages to be a unique and meaningful experience, regardless of comparisons to those other titles.
The Plane of Spirits puzzles are an excellent addition, and it offers a lengthy experience with unique levels and content. Add to that the game's general style and good execution, and Mini Ninjas is a game that shouldn't be overlooked, even if you have already played the console versions.
