first revealed yesterday, will feature old-school 2D platforming flavor, akin to Super Paper Mario's better moments.
A Japanese fact sheet -- lovingly translated by the NeoGAF community -- describes the gameplay as being largely 2D, with hand-drawn animation and backgrounds, and the requisite Wiimote waggling interactivity (hence the "Shake," we presume). According to the fact sheet (and according to NeoGAF), the game is slated for a 2008 release. You know, for now.
