Donkey Kong , released in 1981, was Nintendo's first major hit. It introduced two iconic characters: Mario (originally "Jumpman") and Donkey Kong. The game follows Mario as he tries to rescue Pauline from the clutches of the titular ape within a set time limit. Once the final level is completed, the timer restarts, increasing in difficulty.
The gameplay revolves around Mario navigating through four industrial-themed levels – construction zone, cement factory, elevator-themed level, and rivets removal on girders. He must avoid obstacles like barrels, fireballs, and spring-weights while searching for tools to aid him. A hammer allows destruction of these hazards for a limited time, whereas finding Pauline's items boosts his score.
Donkey Kong is notable for its narrative elements, presented through simple cutscenes that advance the storyline. Notably, various console and computer conversions omitted certain levels, with the cement factory often left out.
