NEW YORK (MainStreet) — It was a high-flying success. But to the young developer, Dong Nguyen of Hanoi, Vietnam, Flappy Bird, a mini-game sensation, became Frankenstein – a monster creation he couldn't manage any more.

"I am sorry 'Flappy Bird' users, 22 hours from now, I will take 'Flappy Bird' down. I cannot take this anymore," Nguyen told his 126,000 Twitter followers Saturday. "It is not anything related to legal issues. I just cannot keep it anymore."

Dong claimed the globally popular mobile game "ruined his simple life," but he told his social network, "I still make games." Just not the most successful one he had ever created.

The bare bones but addictive app was a best-seller, earning $50,000 a day in ad revenue with more than 50 million downloads, according to The Verge. Flappy Bird was #1 in 137 countries on the iOS App Store and topped the Android Google Play platform as well.

Released in May of last year, the game, inspired by the pixilated graphics and the character "Cheep Cheep" in Super Mario Brothers, featured a crudely drawn yellow bird negotiating a field of pipes. Friends reported that Nguyen had received a warning letter from Nintendo; however, the Japanese game maker said that it was not considering a lawsuit, according to the Daily Mail.

Nguyen claimed to have created the app with just two to three nights of coding.

"I can call 'Flappy Bird' is a success of mine. But it also ruins my simple life. So now I hate it," he said in a tweet dated Saturday. Nguyen has since refused comment to various media inquiries.

A flock of knock-offs have already landed in app stores, hoping to feather their nests since the sudden flight of Flappy Bird.
