SkyWay Onscreen HUD

So this weekend I've got the Xbox 360 controller working with the game, a bit of rumble in there, and I've also designed a prototype HUD for the game, as shown in the screenshot below (click to enlarge).

At the moment the design is still only a prototype, it is more than likely elements will be moved around. The gravity value represents how much gravity is in effect on that level. The exit proximity is basically a level progress bar. The speedometer represents the player's current speed. Finally, the oxygen represents how long the player has left in the level before death (i.e. time limit).
