In an exclusive interview with Forbes , Nguyen stated he removed the app because it was too addicting.
Nguyen states in the interview , that the game was intended to be a relaxing game, played to bring enjoyment, not anxiety. Once he noticed that it was becoming a problem, he decided to pull it from app stores worldwide.
He thanked fans for playing Flappy Bird, Forbes reports, and vowed to continue developing future games. However, he said if any of his games appear to become as big of a sensation as "Flappy Birds" did, he wouldn't hesitate to pull it down.
According to a Reuters report on Yahoo.com , during an interview the developer said the game was bringing in nearly $50,000 a day in advertising. A dollar amount that has many questioning why he would pull such a revenue-building app.
On Feb. 8 2014, Nguyen Tweeted "I am sorry 'Flappy Bird' users, 22 hours from now, I will take 'Flappy Bird' down. I cannot take this anymore."
He said his decision to take down the game had nothing to do with legal issues, such as its familiarly to Nintendo's Mario Bros.
In the game, users had to try and navigate a bird between a series of tubes.
Those who have already downloaded the game onto their smart phones are still able to play it. New users won't be able to download it from app stores as it has already been removed.
