So turns out the Samsung app store still has Flappy Birds. For those who are still looking for the game.  I must say… This game is beyond dumb. Yet I can’t stop playing it. It’s just rather frustrating and the physics behind the game causes headaches. So if you want to time killer, this will be the best game for it.
