New features
All information below was gathered from Neogaf.
 * Trophy levels, said to be "super-tough" stages unlocked from collecting full sets of KONG Letters and Puzzle Pieces. Once all trophy stages are finished, a new surprise awaits.
 * Difficulty settings: Original, as seen in the Wii version, or an Easy mode that increases the life bar to three Hearts per Kong and additional helpful items on sale at Cranky Kong's Shop. These items are stated to allow a recovery from falling down an abyss, grant the Mine Cart and Rocket Barrel more durability, and allow the usage of a DK Barrel at any point during a level.
