Marble Saga: Kororinpa is the sequel to Kororinpa: Marble Mania, which hit the Wii shortly after launch. For the most part, the follow-up sticks to the same basic play mechanics behind the first, but developer Hudson has gone back and fixed a few problems, as well as introducing a few new features as well. The biggest of these new features are stages designed specifically for the Wii Balance Board. Compared to the Wii-mote only stages, Balance Board stages feature a simplified design, but with the added challenge of having to use your entire body to balance the levels. Anyone who has played the ball balance game in Wii Fit could tell you this is no easy feat.
