This was only Kirby's second game, and it manages to do 100x better by introducing abilities, which are not only fun to use, but also bring a bit of challenge to the game, because you may lose an ability after one hit. Again, I never grew up with the NES because I was born in 1991, but I might as well call Kirby's Adventure the best NES game I've ever played.
My rating: 9/10
