Nguyen (Flapper Bird creator) has followed through with his threat. Flappy Bird is no longer available on the iTunes App Store or Google Play as of Sunday afternoon.
The notoriously difficult game gained popularity just a few weeks ago, which brought it to the top of both the iOS App Store and the Google Play Store. What could have prompted him to take the game down? He simply said: "I can call 'Flappy Bird'...a success of mine. But it also ruins my simple life." on Twitter.
Here's original story from the Verge :
Flappy Bird creator Dong Nguyen has said that he will take the game down — presumably removing it from the iOS and Android app stores — tomorrow for reasons unknown. On Twitter, Nguyen, whose surprise hit is making $50,000 a day in ad revenue, said that he "cannot take this anymore" and would remove the game 22 hours from now, or midday Sunday. He ruled out a couple of the most obvious potential explanations, saying that there were no legal problems, the game had not been acquired, and he had not quit making games.
