Funny, but here's how you could make it better...
Have you seen Rise of the mushroom kingdom? If you haven't, go watch it, tis a very good flash. Now, ROTMK has this very detailed plot, and I suggest you work on that if you continue with a kirby series. Have some sort of conflict, okay? Let's say, King Dedede becomes very powerful, and kills/destroys something that Kirby loves. Kirby now has a reason to mutilate Dedede. Now, if you could just improve your graphics a bit more (kudos on the improvement, btw.), you'd be set. Oh, and one last thing, try and include some hats in there, kirby swallows things and gains their abilities, that's how he fights.
