Touch Arcade has a slew of new screenshots from an upcoming free update for a game I've been coming back to more and more lately on my iPhone: Zen Bound. When I first installed it, I thought of it as more of a tech demo than a game, but as you load it up more and more, you really do start uncovering layers of competition -- "if only I twisted the statue that way I could cover more ground, or maybe if I started from that leg I could wrap around closer on that side." It's pretty addictive, and it's one of those games that starts tugging at your mind even when you're not playing it.
The update probably won't help free my mind -- not only will it have a whole set of new objects to wrap up (featuring some fun retro-gaming themed pieces), but it's getting some bugfixes and some performance tweaks as well. The paint spread by the rope will be smoother, and the problem of the rope crossing through objects should be better (while that happened from time to time, it wasn't a huge complaint).
Still, especially for free, it sounds like the update will only make a great game better. Zen Bound is available right now in the App Store for $4.99 (with the free update available "soon"), and there's a lite version to try out as well.
