From Nintendo: The simple controls for DK Jungle Climber really set it apart and make it
accessible for non-gamers. Players only have to worry about three buttons: The
L Button controls Donkey Kong's left hand, the R Button controls his right
hand and the A or B Button is used for jumping attacks. As Donkey Kong spins
around pegs on his climb, players have to time his release just right to send
him flying.
