Flappy Bird developer Nguyen Ha Dong on Saturday surprisingly announced via Twitter that he will remove the popular game from app stores in following hours, and he kept his promise, as the game went down both in the App store and in the Google Play Store at midnight local time on Sunday. “22 hours rom now, I will take ‘Flappy Bird’ down” Dong said on Twitter. “It is not anything related to legal issues. I cannot take this anymore.” However, that doesn’t mean the game is completely unavailable. Anybody who has downloaded the game before being removed from the stores can still play it on the devices it was installed on. In fact, some individuals decided to auction on eBay
