Stage 6-4

Stage 6-4 is the fourth stage in the Airplane in the Game Boy version of Donkey Kong. The stage is a boss battle with Donkey Kong.

Layout
Mario starts on some ground on the right. Wind blows Mario to the right throughout the level so he has to fight against the wind, and Donkey Kong constantly pulls the switch that changes the direction of the Conveyor Belt near the end of the level. Mario has to Jump onto the moving platforms once they are close to ride them. Mario must constantly fight against the wind so he does not get blown off the platform into the Spikes. He must crouch under the bullets the cannon so he does not get hit. Once he is far enough to the left, he must go down to a lever, then pull it to activate the stationary platform and wait for it to come close. Once the moving platform is close enough, Mario must jump onto it then ride it up while watching out for the Spark on the platform in the middle and the cannon's bullets. Once he is at the top, he must go left on the conveyor belt, then jump up to Pauline to end the level, with Donkey Kong taking her away again.

Enemies

Cutscene after level completion
Donkey Kong is behind some energy-shooting cannons, he watches Mario avoid the shots by the cannons while fighting against the wind. Mario struggles a bit with the two obstacles but is eventually able to jump onto first cannon then the second cannon. Donkey Kong, shocked by this, continues to run with Mario giving chase. The player is then given lives based on their score.
