A design choice in upcoming Wii U title Donkey Kong Country: Tropical Freeze is indicative of the struggles even first-party developers are enduring with Nintendo's console.
As noted by NintendoWorldReport, when playing the game on a TV screen the screen on the Wii U GamePad is left completely blank.
The game supports off-screen play, meaning users are able to play it in its entirety via the GamePad, but when playing on the big screen it’s unusual for the GamePad to display nothing at all.
Some titles such as Deus Ex: Human Revolution and LEGO City Undercover offer GamePad-specific features and those that don’t will sometimes mimic the TV display on the peripheral, or offer additional optional features such as displaying a map.
Donkey Kong will be the first to simply leave the display blank, however.
Some Wii U owners have called for the option to disable the GamePad screen when not in use to save on battery life
