Captain Toad: Treasure Tracker is an experiment for Nintendo. It's an upcoming 3D puzzle game for Wii U, spun off of the "Captain Toad" levels from last year's acclaimed Super Mario 3D World. It's essentially a puzzle-platformer in the Mario vein, with one radical change: There's no jumping in the game.
It's a new approach for Nintendo EAD, the developer of acclaimed main-series Mario titles Super Mario Galaxy 2, Super Mario 3D Land and Super Mario 3D World. When you think about how central Mario's jump is to this kind of game, and to a Mario universe title specifically, you begin to get an idea of just how different this is.
