From Nintendo: What at first glance appears to be a 2-D sidescroller ripped straight from the pages of the Paper Mario universe soon turns into a 3-D action-adventure that defies all video game logic. Fusing 2-D and 3-D perspectives, not to mention RPG and platformer elements, the game slips back and forth between dimensions. The action sprawls across eight worlds filled with raps, puzzles, bizarre mysteries and items that often draw themselves out of thin air.
