After giving out a warning yesterday, Vietnamese developer Dong Nguyen from dotGears has taken down mobile game Flappy Bird from the iOS and Google Play stores. The said game hit the top spot on both app stores, but Nguyen had expressed frustration on Saturday by tweeting, "I cannot take this anymore," according to VentureBeat.

Flappy Bird had been reportedly downloaded 50 million times, and most of those occurred in the past few weeks only. Nguyen initially enjoyed the sudden popularity of his game. However, he also got lots of criticisms because the design looked similar to that of a Ninento Mario game, the report detailed.

Nguyen did not give additional explanations for his decision to remove Flappy Bird. He did say it was not for legal purposes, but he had also previously voiced out his frustration with the criticisms being thrown at him. For Nguyen, taking the game down means giving up around $50,000 daily revenue from in-app advertisements, the report explained.

Users who have already downloaded Flappy Bird can still play it, but the app is now unavailable for downloads in both iOS and Google Play app stores, VentureBeat reported.
