I loved this! It's mostly because of the slick animation. It wasn't sprites, but it seemed to be imitating them. I just loved seeing how fast paced this was. I wish I knew the names of these enemies. I never played Kirby as a kid.
It's fun no matter what you played. The music was great too. My favorite part might have been when he blocked the cannon. I thought he was gone for at one point. Well, he kind of was a the end. Still a great cartoon.
