From the review: "Jetpack Joyride is a side-scroller where the object is to make it as far as possible while avoiding zappers, lasers and missiles and collecting as many coins as possible. The controls are simple, you touch the screen anywhere to make the jet pack move up, and release your finger from the screen to lower your jet pack. If you’re hit once, it’s game over. Pretty simple! If this was the entire premise of Jetpack Joyride, I would be fairly satisfied with it. It would be a great time killer game that would keep you hooked; the type of game you wouldn’t want to put down because you know the next time you could beat your previous record. But Jetpack Joyride actually takes it a few steps further by adding a few other elements."
