'Flappy Bird' Removed from App Store by Developer
Nguyen had previously expressed frustration at the attention he has received since the sudden popularity of his game. In a tweet last week he said "Please give me peace.", and yesterday, he announced that the game would be removed from the App Store today.
Flappy Bird no longer shows up in search, developer's app listing, and Top Free games. The direct link for the game still shows in the App Store at the time of this writing, but is unavailable for download.
In subsequent tweets, he said the removal was not due to legal reasons and that he was not interested in selling the game.
If you already have downloaded the game, you can still play it even though its been removed from the App Store.
