Throughout the Flappy Bird ordeal, Nguyen has been reticent to give interviews to the media, but he broke the rule for a chat with Forbes.
“Flappy Bird was designed to play in a few minutes when you are relaxed,” Dong told the site. “But it happened to become an addictive product. I think it has become a problem. To solve that problem, it’s best to take down Flappy Bird. It’s gone forever.”
Dong previously tweeted that the game "ruins [his] simple life," but both he and Nintendo have denied rumors that Flappy Bird was taken down for legal reasons owing to the similarity of some of its graphics to those found in Mario games.
Forbes got the interview on the condition that they not reveal Dong's face, though the report says he appeared "stressed." Dong had apparently recently met with Vietnam's Deputy Prime Minister Vu Duc Dam, and his parents had only just found out about Flappy Bird—on the news, no less.
He added that he's relieved he took the game down, and that he would do the same to his other games, Super Ball Juggling and Shuriken Block, if they too became "addictive."
