Months ago we took a look at 'Descent', a 3D racing clone that pits you in a high-speed "tube" for some dizzying adventures.

Fast forward to today and 'Space Tube' hits the Marketplace for a pricey $2.99. However, this game is a little more polished: better music, easier controls, better graphics (for cut scenes, at least) and more robust game play. We took it for a spin and enjoyed it, though found the price a bit high. The game has a trial available, which we recommend you at least give a try.

Try it out here in the Marketplace.
