Kidnkid.com started out as an internal team at J3 Entertainment, but went independent after its first title was completed1. The "kiddie platformer" boom in the early 2000s was generally attributed to Kidnkid.com2, after their adaption of the animated film Hayan Maeum Baekgu ("White Heart Baekgu") sold more than 120,000 copies, figures even the most popular big budget titles in Korea could only ever dream of (later the company claimed even 300,000 sold copies 3). The success of Baekgu caused dozens of imitators, both in the general "kiddie platformer" genre, as well as at least half a dozen direct plagiates4.

Eager to repeat the hit, Kidnkid went on to produce a sequel, but there were complications: Sonokong had actually acquired the licensing rights for the character and sublicensed rights for a PC game to Kidnkid.com, who created the first game, published by Hanbit Soft, and registered a copyright for games with that title. Sonokong was not amused about one of their contractors hijacking what had turned out a cash cow, engaged in litigations against Kidnkid.com and won5. Sonokong subsequently produced and published the sequel themselves6. Kidnkid.com reacted with a countersuit, and only a month after Sonokong's Baekgu 2, Kidnkid's Hayan Maeum Baekgu 3 was published through Bisco7. It appears in the end the two companies settled, as the inevitable Baekgu mobile game was released by Sonokong on December 12th, "Licensed by Kidnkid.com"8.

Kidnkid.com eventually abandoned kids' games and was appropriately renamed to Nlogsoft on March 22nd, 20049. Under the new banner they went on to produce one of Korea's very few indigenious PS2 titles, and a network game to boot. In 2007, however, the company seems to have stumbled over conflicts with CDC Games, the Chinese publisher of their MMORTS Darkness and Light(Battle of Shadows in the US)10. At any rate the company disappeared soon after the annulment of the contract, which was followed by the discontinuation of Darkness and Light's beta phase by April 200811.
