DK: King of Swing GBA comments

The normally quiet jungle is abuzz with excitement, because it's time for the
ceremony to choose the king of the jungle. Or at least it would be if King K.
Rool hadn't stolen the special medallion meant for the winner. Donkey Kong and
his friends must swing their way through the jungle to get the medallion back
and, along the way, battle with King K. Rool’s minions.

You'll guide Donkey Kong through a number of puzzling stages, grabbing
bananas along the way on your quest to reach the goal. Using just the L and R
buttons to grab with Donkey Kong’s left and right hands, DK spins on the pegs
and lets go to launch up into the air to reach another peg.

The game features many elements that take advantage of this unique game
mechanic. Spinning left or right on a crank opens or closes doors, and spinning
on bolts slowly loosens them until they pop out, making Donkey Kong lose his
grip.
