Original "Flappy Bird" can still be downloaded, and yes, it was never pulled (completely)
Who says Flappy Bird is gone? I don't think so. Recently I tried downloading it from my purchases and yes, it is still downloading, and that makes me think that it was never pulled by the developer, or hasn't yet been deleted. Try if you can also download it or not.
