It's been nearly six months since Flappy Bird officially ended its meteoric rise up the mobile app store charts, taken down by Vietnamese creator Dong Nguyen out of discomfort with the game's addictiveness and unanticipated attention from fans and haters. Now, after hinting that the game might return in the future, sequel Flappy Birds Family has quietly appeared in the Amazon App Store, touting its compatibility with the Fire TV set-top box.

The Amazon page suggests compatibility with "Android 3.0," but the game doesn't seem to be installable on any device except the set-top Fire TV. The listed developer, Dotgears, has one other Fire TV game to its name, the Nguyen-developed Super Ball Juggling.

Flappy Birds Family's product description from Amazon touts "incredible new features" such as "Person vs Person mode, more obstacles, more fun and still very hard." In addition to local split-screen multiplayer and multiple colored birds, the game now has floating, cloud-shaped ghosts to avoid and standard Mario-style pipes. "Enjoy playing the game at home (not breaking your TV) with your family and friends," the description says.

While Flappy Birds Family is free (like its predecessor), the game doesn't sport the kind of ads that made Nguyen a reported $50,000 a day for the first game. That might suggest that Family is coming to the Fire TV through some sort of paid exclusivity deal with Amazon, which is trying to differentiate its video-player-meets-casual-games-console with exclusive content from in-house studios. If that's the case, though, it seems off that Amazon isn't loudly trumpeting that fact with any sort of announcement or press release at this point (Amazon did not immediately respond to request for comment). Or maybe the game will be showing up on iOS and Google Play stores before too long and the exclusivity is temporary.

Flappy Bird is definitely the kind of big-name exclusive that could get people to take a second look at the gaming potential of Fire TV, but we're not sure it's going to prove to be the killer app that Amazon seems to want it to be. Even with the new features, there's a big difference between a mobile time-filling game that became a phenomenon and one that will appeal to people sitting in front of the humongous flat screen TVs in their living rooms.
