Nintendo has now addressed that with a new downloadable content, DK Island & Emerald Rush. The stuff added offers a variety of delicate twists and variations on the game systems showcased across the main game, all crammed into a vaguely roguelikey framework. In Emerald Rush, vast amounts of emerald material appear across the map. Initially this all happens on DK Island, but as you progress you'll gradually unlock versions of this mode across many of Bananza's different 'layer' levels. With this article going live just two months after my pre-release review of the base game, clearly that wasn't the case with DK Island & Emerald Rush - but that knowledge also works against my impression.
