A few points to compare the two: - Jetpack Joyride is way easier. I think something "unique" about Flappy Bird is how difficult it is. - It's extremely easy to start a new round in Flappy Bird (and it happens quite often). Die on the first pipe? Tap again to jump right back in. You don't even need to hit a button, it's pretty much tap anywhere on the screen. - Sharing high scores with friends is way easier. "I got a 22 the other day." is way easier than saying "I got 108,000". - The high scores are more meaningful to other players because they will know exactly how Player1 got that score. The 108,000 in Jetpack Joyride is ambiguous because the score is a function of distance, coins, kills, etc. Remember back in the day, hearing about some dude's cousin that made it to level 55, and how seemingly impossible that was?
