I hope Kirby is good.
Not that I'm a Kirby fan but I play a game once every couple of years. For what it's worth this is definitely one of the better games in the series and my favorite in recent memory. It's exactly what bork laser said; the game is unfortunately a little too easy (surprise surprise) but the variety of powers is awesome and the new hypernova ability (the one where Kirby sucks everything up) is hilarious and fun to use. Unlike Mario's super mushroom they actually utilize hypernova quite a bit and it's great being able to power through a section just inhaling everything.
There are a few mini-games to play as well. Although I'm not far enough in to unlock all the mini-games, but from the start you can play a weird platforming taiko style drum game which is entertaining and a smash bros. styled combat game where you can select from a series of different abilities to fight your friends or the CPU.
There are keychain collectibles that can be found throughout the levels and it's a neat system with a bunch of standard keychains littered around the environment while the rare ones are usually hidden away in some light puzzle-like scenario. I also enjoy the attention to detail they've put into the keychain menu where tilting your 3DS causes all the keychains to sway about. It's indicative of another facet of the game, this is an incredibly well polished and and thoroughly detailed game.
