"Much as we may not like to admit it, Flappy Bird was a legitimately clever game. Taking its extraordinarily simple premise, it wrapped the challenging gameplay in a coat of exceedingly charming paint, masking the constant frustration it ought to have elicited and instead gave players the drive to do better. Within the confines of cheap, too-close-to-Mario sprites and one-note gameplay, it garnered a massive following as people joined together to play with – and against – their friends. Flappy Bird worked because it was simple. It did exactly what it needed to do; had it been any more fancy, any more complicated, any more detailed, it would not have become the phenomenon that it was."
