This is actually pretty cool. It's nice to see an animation this long that doesn't rely on 5 second stills with maybe a character blinking to pad length.
My favorite part is the bird's eye view of Kirby actively fighting and dodging. I have this thing for fight scenes not being interrupted by scene cuts, and that part, to me, was lovely.
Some scenes confused me a bit. For example, I don't really see how Kirby ended up on one of those unicycle/motorcycle things. A quick shot of him swinging onto it would be enough. I can't remember the transition you actually used off the top of my head.
Speaking of that, how about a replay button?
Lastly, while the music was good on its own, it felt like it would fit more with a monochrome samurai-style clip rather than a colorful Kirby flick.
