Platform game
A platform game, or platformer, is a genre of video game. Platformer gameplay is about jumping between platforms or over obstacles. The player controls these jumps and must use skill to avoid their character falling off of platforms or missing jumps.  This kind of gameplay, even in other genres, is called "platforming". Games where jumping is not controlled by the player, such as The Legend of Zelda: Ocarina of Time, are not thought of as platform games.
