I usually dont like stick-flicks
This one was pretty good though, perhaps not the animations or graphics, or story (it is a stick movie for chirst sake). However, I really liked the effect in the "Caution (lol) colorless area!" where the white ninja blended in the light and the dark ninja blended in the shadows. Especially when they were running ;)
The end was a bit unsatisfactory though. If you do a sequel, more fighting in the colorless area is mandatory!
