He might be small, but he's one angry Ninja!
The graphics in I-Ninja are some of the crispiest, most vibrant visuals since The Wind Waker. Sure, many levels may be a bit too "game-y", but chances are you'll be too busy admiring the beauty around you to care. The game's music is theme appropriate, and even a bit catchy. Voices are extremely sparse, but what's there is well done – you've got to be quite the grouch to not crack so much as a grin the first time Ninja screams "NINJA FURY!"
Overall, I-Ninja earns its black belt in the art of platforming, even if it is a bit on the short side. The challenge-hungry may find it too easy and forgiving, but most action gamers will find the game worth a purchase.
