In this brain teaser, you control a marble. No, actually, you control gravity. You tilt gravity to make the marble roll through mazes. Over and over. Is it repetitive? You bet. Addictive? Absolutely.
If you get tired of playing as a marble, you can choose to roll around a meowing cat, an oinky pig and other cute, round creatures. Some animal marbles roll faster or slower than others.
Your marble always starts someplace silly, like rolling along an empty highway suspended 40 stories in the air. You balance and twist your Nintendo Wii remote in your hands, and the game reads those movements as a means to change gravity. Changing gravity forces the marble forward, back, left and right along the highway's curves.
There are lots of obstacles. Potholes. Killer laser beams. But it's the gravity that gives you fits.
Other reviewers seem to enjoy the game but knock it because it offers only several dozen marble courses. But I'm giving Kororinpa a solid thumbs up, because I can play a lot of these courses repeatedly by using faster-rolling marbles, and it's a good player-vs.-player game.
