Dong Nguyen has pulled an intervention on his mobile gaming fans.

The Vietnamese developer is the creator of the wildly popular Flappy Bird game, which has so far been downloaded more than flapbird150 million times on Apple and Android devices since launching as a free app less than a year ago. So popular was Flappy Bird that it was earning Nguyen an estimated $50,000 a day from ad impression revenue.

Apparently Flappy Bird was just too popular for Nguyen, who this week sent fans into a panic by announcing he would stop making the game available for download. It’s become “an addictive product,” he tells Forbes.

We can’t help but wonder what the, well, flap was about. Flappy Bird’s popularity does read like something out of a “Star Trek” episode. But it had a long way to go before catching up with Candy Crush Saga, which has been downloaded onto mobile devices a half billion times since launching in 2012.

Nguyen tells Forbes he will continue to develop games. And Flappy Bird isn’t going away anytime soon; the game is still all over the web, in various forms.
