Representation: Bag-of-words 5 On Feb. 8, Dong Nguyen announced that he would be removing his hit game Flappy Bird from both the iOS and Android app stores, saying that the success of the game is something he never wanted. Some fans of the game took it personally, replying that they would either kill Nguyen or kill themselves if he followed through with his decision. Frank Lantz, the director of the New York University Game Center, said that Nguyen's meltdown resembles how some actors or musicians behave. "People like that can go a little bonkers after being exposed to this kind of interest and attention," he told ABC News. "Especially when there's a healthy dose of Internet trolls." 7 February 2014 is going to be a great day in the history of Russia with the upcoming XXII Winter Olympics 2014 in Sochi.
