Donkey Kong is one of the earliest examples of the platform game genre; it is sometimes said to be the first platform game, although it was preceded by Space Panic. In contrast to Space Panic, however, Donkey Kong was the first platform game to feature jumping, introducing the need to jump between gaps and over obstacles or approaching enemies, setting the template for the platform genre. Competitive video gamers and referees stress the game's high level of difficulty compared to other classic arcade games. Winning the game requires patience and the ability to accurately time Jumpman's ascent. In addition to presenting the goal of saving the Lady, the game also gives the player a score. Points are awarded for finishing screens; leaping over obstacles; destroying objects with a hammer power-up; collecting items such as hats, parasols, and purses (apparently belonging to the Lady/Pauline); and completing other tasks. The player typically receives three lives with a bonus awarded for the first 7,000 points, although this can be modified via the game's built in DIP switches.
