Kirby was the first (and, for all practical purposes, only) character I chose playing Super Smash Bros at my friend's house when I was a kid. I loved going to her house, because I got to be Kirby! And I remember she had an original Game Boy and a Kirby game that we would play on class trips... Oh, Kirby. So amazing. Such practical powers, too!
So no, not a fanatic. But I definitely see the appeal!
Only vaguely related, but I highly recommend the game "Leo's Fortune" from the apple app store (for ipad, iphone, etc). It's a platformer with a character who has similar powers... The puffing jump thing? That was one of the things that made that game so fun for me, haha.
