I really liked this and it's actually kind of hard for me to say why. I think it's just because the animation is so good. It was great to see sprite work with the standard 2D stuff. Then again, maybe that was just low resolution. The two can overlap. The voices were quite good.
It just seemed to fit the Kirby games. Granted, I've never played any of those. Well, I think I've played as him in "Super Smash Bros". I just appreciate how authentic it seems. It's nice to see all these characters.
