Not bad... Actually, it was pretty cool.
Before i begin my review, i'm going to be blunt. The graphics sucked, they looked really bad dude.Some fo the effects you used like the Chidori came out nice though. Okay, review. It was bad at all.. Your definitly new to flash, and that isn't bad. Everyone starts somewhere and for a first finished project, i quite liked it.
The sound wasn't bad, the sound track got abit annoying and didn't fit a fighting scene.
Story. You ripped it off the manga/anime and tried to recreate it. It wasn't bad but it was annoying when you went to describe the mangekyou sharingan.
Overall, not bad. Just, try to improve on the art and work on a orginal storyline. Music could have been more darker.
