Ain't nothing powerful about this one.
The game lets you play as either Naruto or Rock Lee, you'll have to play as both in order to progress however, and it more or less follows the story up to the Pain arc, with a couple of extra stages featuring latter events. Regardless, it's a very loose retelling, in a more "humorous" fashion, however, it falls flat on it's face most of the time. Gags are very formulaic, usually one of the boys will act in a ridiculous manner and one of the girls will explain why it's supposed to be funny, but it's not and rarely ever is. This is supposed to take after the Japanese humor routine of the "Funny guy" and "Serious guy", the girls always taking the Serious guy's place and the boys the Funny guy's, but the game is rarely ever funny. There's a lot of crossdressing humor and the kind of jokes they'd pull on filler episodes to retain their younger audience. Still, there are a couple of jokes that might make you smile, but they don't make up for the rest of the game.
First, let's go over the good things about the gameplay, experience points. Beating each stage grants you Experience Points, and before each stage you can actually take "Personal Challenges", there's about six per stage, but you can only attempt one per go, that multiply the experience points gained, and there is no penalty for failing them. Now, these experience points can be spent on a pretty nice variety of parameters, be it your level(raises HP and attack power), resistance to status effects(Poison, paralyzed, etc), skills or even one-time use bonuses. Even better, you can reallocate points however you see fit, except the ones you spent on one-time use, those are gone for good.
The game's best feature, by far, are the graphics. Animation is pretty smooth and charming, and the characters look impossibly cute. The style they used for the sprites makes them look as if they were ripped straight from a TV show, this game is pure eye-candy, plus, turning the 3D on doesn't affect the framerate in the slightest. Sound is alright, music is the usual filler music they use for this kind of licensed games, and each character has a couple of voiced lines, and that's about it.
