The game, which involves tapping the screen repeatedly to control the flight path of a bird through obstacles, seems simple enough however thousands of people have taken to Twitter to release their frustration at the addictive and difficult game.
One user on the review section of the App Store wrote, “I haven’t slept, I used to sleep like a baby. Now I can’t,” they wrote. “I lie in bed, I can hear flappy bird taunting me to try and beat my score again. when I close my eyes I see flappy bird. I haven’t eaten. I see flappy bird in the food on my plate. I hear him in the voices of those I love” and that the game is “life ruiningly addictive”.
