Hey, I just looked at it, and Jetpack Joyride does not have the same control scheme. It is the "hold button to accelerate up at constant acceleration" controls like other previous games, not the Flappy Bird's "tap to give a sudden impulse" scheme.

Edit: Actually, it's a combination of many schemes. There's a gravity suit that inverts gravity. There's jumping from the ground, which is impulse-based. But the generic jetpack flying is acceleration-while-holding-based. Bottom line, I would not say it's "exactly the same idea" as flappy bird at all.

Interesting. It seems feasible that the cute graphics and memorable name play a role.
