"22 hours from now, I will take 'Flappy Bird' down," Dong said adding: "It is not anything related to legal issues."
"I cannot take this anymore," he wrote. Flappy Bird has caused a sensation after rising out of obscurity to become one of the most downloaded mobile games on both Apple and Google's online stores.
Users have to steer a bird between green pipes. The Android version has been downloaded up to 50 million times, and attracted more than half a million reviews.

Many people have been questioning Dong on Twitter about his decision to take down the game as only a day earlier he had been talking about developing the game for Microsoft's Windows phones.
Dong could not be reached for comment. He had turned his telephone off after cancelling an interview with Reuters on Thursday and not finalizing arrangements for one on Friday.
