JiG: "The concept is simple. You play a shining, heroic yellow ball who launches through space and collects the various coins peppered throughout the game's 100 levels. To do this, you'll need to use the [Left] and [Right] arrow keys to set your angle, and press [Up] or [Down] to adjust your force, all of which can be seen in the panel at the bottom of the screen. (Alternately, if the [arrow] keys aren't your thing, you can type in these numbers manually in their respective boxes, or drag the gauges with your mouse.) Once you're satisfied, it's time to hit the [Space] bar to fly towards the goal point in each stage. Of course, nobody ever said gravity was easy to deal with. The bigger the object, the stronger the pull it'll have, and the more force you'll need to be able to break free, rather than smashing into it, thus putting an early end to your lucrative career in space coin scavenging. You'll encounter a number of obstacles, such as red planets that repel you and blue planets that will draw you in."
