A game so utterly devoid of challenge that actually calling it a game almost seems too generous. There's just nothing here beyond a monotonous, pedestrian affair, and it can be completed in a couple of hours with only the slightest of efforts.
Just a very, very bad game. The included battery save feature is about the only good thing about it, since it means that you can shut the game off without fear that you'll have to retread the same boring levels next time you pick it up.
Even the most die-hard fans of the series will quickly become disappointed and bored to tears soon thereafter. Very little effort was put into the games design or implementation, so you shouldn't put any effort into buying it.
