The game's only redeeming factor is the co-op mode. At any point, if a second player wants to join in, all they need to do is turn on their Wii Remote and a second Niki avatar is spawned on the screen. When players team up, they can more quickly complete levels and assist each other in getting to harder-to-reach spots in the levels. The only drawback of the mode is that players must tolerate a further zoomed-out view of the stage as they move further away from each another.
Don't be tempted by Niki - Rock 'n' Ball's budget price. The game is partially broken, uninspired, and most important of all, boring.
