Conceptually, the game is rather easy to grasp. Once again, players are tasked with getting monkeys (that are mysteriously trapped in plastic balls) to a goal by tilting the game world. This time around, the game can be controlled through shifting your weight on the Balance Board -- the translation should be immediately apparent.
Perhaps masters of Wii Fit (and subsequent fitness-related knockoffs) should find no problem with Step & Roll. However, a Balance Board novice like myself was a bit overwhelmed by the sensitivity demanded by the game: it takes subtle shifts in weight to carefully control the monkeys. Instead, my exaggerated movements caused the board to jerk around, tossing the trapped simian around haphazardly through the course.
