Stage 1-1

Stage 1-1 is the first actual stage of the Game Boy version of Donkey Kong. It marks the first area of Big-City; on the level map, it is located on the edge of an avenue, which goes along the front of a grand building. In the stage, Mario sets off to rescue Pauline from the mean, wretched Donkey Kong. The ape shows off at the beginning of the stage, hurrying with the damsel in his sturdy arms to a shallow metallic door. He manages to enter the door with the girl, and once inside, Donkey Kong locks it. While Pauline is yelling frantically for help behind the closed door, Mario reaches the place; being in such a desperate situation, the plumber seeks for anything that could help open the door - which is, basically, his goal in the level. With not much effort, he manages to find a big key, which will aid him in the opening of the solid entrance.

Layout
The level starts with a trash can which sits on the foundation of the level, right next to a ladder. A Bowbow lumbers in a further place, near the locked door of the stage. The mentioned ladder connects the ground with a girder platform, which is, in turn, connected with another larger platform through another ladder. Up next, on the second platform, ascends and descends an Oil enemy - a hammer sits near it. The hammer seems to host a long ladder, which grants the hero new, high-placed platforms. To the far right, there is a narrow pit, whose walls prevent the key of the level from falling. A girder platform stays right under the key, and underneath the platform, sits the level's foundation with the locked door.

Pauline's lost items
Within this stage, Pauline's lost items can be found in the following order and in the following places:
 * Hat: right above the second Bowbow in the level, which stays on a girder separated by the second lowest platform from the left through a small slit.
 * Parasol: above the left highest girder.
 * Bag: stays in front of a window above the third highest platform from the right.
