Really great game. A culmination of every game that's come before it, resulting in one of the best Kirby games ever. Gameplay is incredibly smooth (though I still slightly prefer the movement of the Flagship games), the abilities are expanded and have a lot more to them, the collections of games are all fun with unique gimmicks to keep them interesting, the bosses are good and have some of the best in the series, and overall the game just has so much charm to it.

I can truly appreciate this game for all it's done and how much it's influenced the Kirby series; and I mean both the original Super Star and the additions in Ultra. The expanded abilities, the Halberd, Marx, Novas, and much more all came from the original, while Masked Dedede, Galacta Knight, The TRUE Arena (and the general difficulty of the mode), and the Soul bosses (Canvas Curse did do a soul boss first, but this was the first game to put in in a mainline game and make it more "final boss but harder and with more moves" rather than "completely original sentient ball fight", though the latter would continue to return in later games) all came from Ultra.

Also final note, this is the first Kirby game in the series where I truly went out of my way to get 100%. I had fun the entire time, and beating Marx Soul for the first time was incredibly satisfying. Also, shout out to Blade Knight for sticking with me all the way through Meta Knightmare Ultra without leaving me once. You deserve more attention.

Overall, this game is really good. Even if you're not a Kirby fan, this game is very much worth checking out.
