One of the games I was always willing to replay on my 3DS, over and over again. Every level is unique and slowly tells a story in each world, ending with a unique boss. It's a perfect game difficulty wise. It will fuck you up in some parts but is so satisfying you'll keep coming back. Only better game featuring the familiar ape is Tropical Freeze, improving upon this game in every way, though still owing its existence and identity to this game. Donkey Kong Country kicks 2D Mario in the trouser. Play the 3DS version and beat it as many times as I have.
