Update - Feb. 9, 12:54 p.m. ET: Flappy Bird is now gone from the App Store, after being the No. 1 download for almost a month.
The game is missing from "search, developer's app listing, and Top Free games," according to MacRumors.com.
Nguyen Ha Dong, the indie game developer who created overnight hit Flappy Bird, just tweeted that he is planning on taking the game down tomorrow.
I am sorry 'Flappy Bird' users, 22 hours from now, I will take 'Flappy Bird' down. I cannot take this anymore.
Although some people have accused Dong of ripping off other games, he said the decision was not because of a legal drama.
It is not anything related to legal issues. I just cannot keep it anymore.
The 29-year-old from Hanoi, Vietnam, created the game last May, but it surged in popularity early this year. The Verge reported it earns $50,000 a day in ad revenue.
I also don't sell 'Flappy Bird', please don't ask.
And I still make games.
A few hours before, Dong tweeted that the game has ruined his life.
I can call 'Flappy Bird' is a success of mine. But it also ruins my simple life. So now I hate it.
He's also recently expressed frustration at all the attention garnered from the game's popularity.
Press people are overrating the success of my games. It is something I never want. Please give me peace.
Despite the seemingly imminent shut down, Flappy Bird seems to have recently gone under renovation.
Pipes look more polished, the background oscillates between night and day, and Flappy Bird changes between red, blue, and yellow.
In the meantime, devoted fans have begun tweeting #SaveFlappyBird.

Dong did not reply to an email request for comment.
Update - Feb. 9, 6:17 p.m. ET: For those without the game who are dying to play, there's a version you can play on a browser (though it's not quite the same).
