“Flappy Bird” creator Dong Nguyen is back with a sequel to his addictive app. The new  title will launch on Aug. 21 as a free download, and players can pay 99 cents to remove ads from the game.

Nguyen’s new game is called “Swing Copters,” a vertical-scrolling game that players tap to control a hat-wearing character and move him from side to side while avoiding platforms and hammers.




Nguyen tweeted about the game on Monday, promising fans the title would be coming to both iOS and Android. 

Nguyen has been under the radar for several months after “Flappy Bird” rapidly rose to popularity earlier this year.

The original “Flappy Bird” was published in May 2013 by Gears Studio, which is based in Vietnam. The game didn’t see immediate success, ranking way down the U.S. game charts at No. 1,368 six months after release. But a month later, the game placed in the top 250 for free apps in the U.S., and in January 2014, “Flappy Bird” ranked as the eighth most downloaded free app in the U.S.

Nguyen, who said that he learned how to code his own games by age 16, surprised players in February when he pulled the game, claiming it was becoming too addictive.

“I am sorry, 'Flappy Bird' users. 22 hours from now, I will take 'Flappy Bird' down. I cannot take this anymore,” Nguyen tweeted hours before removing the app. He also denied that he was asked to remove the app by Nintendo -- a speculation made by many gaming sites -- because it was too similar to the gaming giant's popular, decades-old "Super Mario Bros." “It is not anything related to legal issues," Nguyen said on Twitter in February. "I just cannot keep it anymore.”

At the height of its popularity, "Flappy Bird" was being downloaded 2 million to 3 million times per day in Google Play and Apple iOS stores, and Nguyen was reportedly making around $50,000 a day from ad revenue.
