A cute game that you can play with a friend.
I think my favorite part about this game was the art. Every level has tons to look at, and I found myself playing through levels again just to look at stuff. The gameplay was simple, but fun, and some levels had Kirby transform into different modes of transportation. (I found the dolphin form to be the most awesome.)
Sometimes my boyfriend would play this game with me, and it was lots of fun going through levels together. He also helped me get the extra stars from boss fights to open up the secret levels. I definitely encourage playing with a friend, you can throw them off platforms!
Definitely check out this game! You might even be able to get away with just renting it if you plan on playing it straight through. It took me about two weeks to beat by just playing for a couple of hours every other day.
