Kirby Super Star is pretty great OP. Great Cave Offensive is especially cool what with all the different areas and music and challenges and aesthetics. There were parts in grassy caves, parts in the sky, parts in outer space, and parts in a cool castle area... My only wish would be for it to be a true maze instead of being a linear path between hubs with short offshoots.

Regardless, it's pretty damn unique, and the only other game to try that again was the spiritual successor, Kirby and the Amazing Mirror. Go ahead and play through the rest of Super Star, play Amazing Mirror, and give Super Star Ultra a try someday too! Graphically there was less effort put into that version, but it controls better and has some cool exclusive game modes that are def worth checking out.

Hell and while you're at it, play Kirby's Adventure, too, as it's probably my favorite Kirby game (Nightmare in Dreamland IS a remake of that game, but you ought to avoid playing it first because it's a pretty lazy remake whose biggest perks are simply a superior engine as well as a cool unlockable extra mode. In my opinion the best version of Kirby's Adventure is definitely the port to the 3DS).
