The fine gents at Touch Arcade have the first confirmation and screenshot of the sequel to one of our favorite games of 2009, Zen Bound 2. As you can see above, the new version (on the right) is a little more subdued with a cleaner UI, although Secret Exit stresses that this is still a work in progress (and obviously they'll have new objects to wrap up in rope to score points). But the new engine will be upgraded to use the most current version of OpenGL available in the iPhone, and you can see that on the rope above -- there are cleaner textures, and supposedly it'll move more smoothly as you play.
Looks awesome to us. There still isn't an official announcement yet (this is actually a teaser picture), but that's expected soon, with a release still a few months out. So if you haven't tried out the first Zen Bound [iTunes link] yet, you've got plenty of time to pick it up and get good before the sequel.
