UAI had the only FLAPPY bird game for more than 7 years. Then, with the lucky viral success of Dong Nguyen’s original clone “Flappy Bird”, based on UAI’s previously published title, complete with indistinguishable flight operating characteristics, and now thousands of copycat Flappy clones, there is widespread confusion. The confusion is so extreme that Ultimate Arcade’s own 8-year-old FLAPPY™ game is now often viewed as just another clone and is not yet being allowed by that name in the Apple iOS Store.

I would argue there is an easily distinguishable difference between the viral sensation Flappy Bird and this product. Decidedly telling is the fact that after 8 years, this is when they've decided to try and get their product on the iOS app store.
