Just like any other Kirby game out there (which is good).
There is always a nifty little catch in Kirby games. For example, the combining weapons ability in Crystal Shards, and the teammate maker ability in Superstar. In this game, you can store up to five abilities in your belly for you to use later on. If you have two abilities you don't like, you can combine them to make a random ability. You can also store treasure chests and health, so you have to strategize what you want, and what you don't think you'll need. That's all the touch screen is used for, which is a bit of a bummer, but it still adds a lot to the gameplay.
The game is fairly long for a DS game, with 8 worlds composed of about 5 levels, each which have a cool little boss stage at the end. If you want to buckle down and collect all three treasure chests in every level, it'll add greatly to the replay value. The game is fast-paced, and will constantly keep you on your toes. With tons of enemies, and literally dozens of abilities, Kirby Squeak Squad is a blast to play.
