sprites are nice!
you make wonderful sprites and so far you're the one i find the best in making them. ^^ i'm also a big fan of the Naruto series and I thank you for your tribute to that great anime!
moving on, i think that you may want to improve your camera movements. they could've added more flair in your flash. there were also some strange settings like that weird underground lair which is slightly inappropriate for the fight. i noticed you lacked some sound effects and voice-overs, Naruto kept repeating the same line... which is kind of a distraction. I'm not sure if I'm the only one experiencing this, but I can't see the text. It would've been nicer tif i could see it... I also found the ending a bit strange because I didn't figure out the last part because I couldn't really read the text, you could've improved the ending a bit though. But overall, it's a good flash. Short, but good. Hope this was helpful enough... ^^
