Under this title, Tiger created a handheld game with a scenario and gameplay based directly on Nintendo's creation. Many home computer clones directly borrowed the gorilla theme: "Killer Gorilla" (BBC Micro, 1983), "Killer Kong" (ZX Spectrum, 1983), "Crazy Kong 64" (Commodore 64, 1983), "Kongo Kong" (Commodore 64, 1983), "Donkey King" (TRS-80 Color Computer, 1983), and "Kong" (TI-99/4A, 1983). One of the first releases from Electronic Arts was "Hard Hat Mack" (Apple II, 1983), a three-stage game without an ape, but using the construction site setting from "Donkey Kong". Other clones recast the game with different characters, such as "Cannonball Blitz" (Apple II, 1982), with a soldier and cannonballs replacing the ape and barrels, and the American Southwest-themed "Canyon Climber" (Atari 8-bit, 1982). Epyx's "Jumpman" (Atari 8-bit, 1983) reuses a prototypical name for the Mario character in "Donkey Kong". A magazine ad for the game has the tagline "If you liked "Donkey Kong", you'll love "JUMPMAN"!" "Jumpman", along with "Miner 2049er" (Atari 8-bit, 1982) and "Mr. Robot and His Robot Factory" (Atari 8-bit, 1984), focuses on traversing all of the platforms in the level, or collecting scattered objects, instead of climbing to the top. There were so many games with multiple ladder and platforms stages by 1983 that "Electronic Games" described Nintendo's own "Popeye" game as "yet another variation of a theme that's become all too familiar since the success of "Donkey Kong"". That year Sega released a "Donkey Kong" clone called "Congo Bongo" in arcades. Although using isometric perspective, the structure and gameplay are similar. The Atari 8-bit computer port of "Donkey Kong" contains one of the longest-undiscovered "Easter eggs" in a video game. Programmer Landon Dyer had his initials appear if the player died under certain conditions, then returned to the title screen. This remained undiscovered for 26 years until Dyer revealed it on his blog, stating "there's an easter egg, but it's totally not worth it, and I don't remember how to bring it up anyway."
