Fly in the air and collect coins...
The basic mechanic is that by pressing on the screen, the jetpack's thruster will engage. When the throttle is turned off, gravity kicks in to pull Barry back to the lab's steely floor. There is no control over the x-axis, our joyrider just goes faster and faster until it's game over. Miss some coins and want to go back? Too bad. The trick becomes knowing how to hop over some obstacles and when to hover in the middle of the screen by tapping the throttle button. There are only three basic obstacles: electric fences that form a line to be avoided, red lasers that will appear to take up the entire screen, but will actually only cover the portion of the field indicated by a thinner, warning beam, and missiles which shoot across to take out the jetpack thief after being considerate enough to sound an alarm and put a fat exclamation on the screen to mark its approximate trajectory. At first all of this is easy to avoid and the coins scattered throughout the map are equally simple to gather. But, as you can imagine, it gets considerably more difficult as the game's speed increases.It would not be fair to finish the review without mentioning the in game store. As mentioned before, coins can unlock things but running around in the lab and completing missions is not the only way to get coins. If you want, you can plunk down actual dollars to get fake, virtual coins. The game never expressly told me to use this service, but the coin payout for an average run or rank up is such that it would take about an hour to generate the coins necessary to unlock the more expensive items. It's kind of a shady element to an otherwise great game. But hey, everyone's doin' it, so I guess that makes it OK. At least in someone's mind.
