Flappy Bird is at risk of extinction as developer 'cannot take this anymore'. Dong Nguyen is threatening to take his wildly popular game down despite topping app charts around the world. The game has been downloaded more than 50 million times and creates $50k a day in revenue from in game ads. However the game and its success is not the bed of roses you might expect. Nguyen tweeted 'I can call it a success of mine. But it also ruins my simple life. So now I hate it. People are overrating the success of my games. It is something I never want. Please give me peace'.
