With the demise of the viral yet short-lived 'Flappy Bird,' other indie game developers simply can't help but hinge on the now non-existent game's popularity. The problem is, Apple and Google seem to be opposed to their money-making scheme.

Google Play and the App Store has reportedly rejected several 'Flappy Bird' knock-offs as of late, says Tech Crunch. One such case is Ken Carpenter of Mind Juice Media's 'Flappy Dragon,' which was rejected by the App Store and taken down by Google Play.

"This is just not my f**king week: Rejected. "We found your app name attempts to leverage a popular app." Which app? FB doesn't exist!?!?!," Carpenter tweeted.

According to Tech Crunch, the App Store has sent Carpenter a notice on why 'Flappy Dragon' actually got rejected:

22.2: Apps that contain false, fraudulent or misleading representations will be rejected
22.2
We found that your app, and/or its metadata, contains content that could be misleading to users, which is not in compliance with the App Store Review Guidelines.
We found your app name attempts to leverage a popular app.

'Flappy Dragon' was also not so lucky at Google Play after the game was allegedly taken down a few hours after it was submitted.

"There was no 'Fair Warning' email, which Google claims to send before taking such actions. I checked and rechecked my spam folder to be sure. They just arbitrarily removed the app with no warning," Carpenter told Tech Crunch. 

"The message they sent me simply referenced the 'spam' provision of the Google Play terms and did not specifically call out what my transgression was," he continued.

Though 'Flappy Bird' knock-offs on the App Store and on Google Play seem to be running out of luck, clones of the Dong Nguyen game can still be played online.

Sesame Street has created their own version of the frustrating game - which they now call 'Flappy Bert' as opposed to 'Flappy Bird.' And yes, Bert actually is carried by a bird through those familiar pipes.

'FlapMMO,' another web-based game also offers an almost 'Flappy Bird'-like experience, says Bloomberg - "except your bird flies in a ghostlike flock of birds controlled by people playing on their own computers."
