Zen Bound 2 came out on the Mac and PC via Steam a few days ago, and to celebrate the launch, the original Zen Bound is free in the App Store for a limited time.
What? You say you already have Zen Bound? Well, not really. This new version of Zen Bound is being self published by Secret Exit and isn't attached to Chillingo in any way. After Chillingo was bought out by EA, a number of developers, most notably Rovio (Angry Birds), have left the Chillingo brand to self publish.
"The average customer tends to associate the publisher brand strongly with the game, leaving the developers into a situation where they are not known for their work. Even when the publisher plays fair and makes certain the developer is mentioned, this message has diminished reach beyond the eyes and ears of the industry." said Secret Exit's Jani Kahrama. "Certainly the change in publisher ownership brought an element of uncertainty into the whole matter, and having your game associated with a thirdparty was not what we considered to be in our best interests."
With this new release, the previous version of Zen Bound will not be updated anymore, so if you are interested in future updates to the App Store classic, it is imperative that you download the new version (again, it's free).
As for the Steam version of Zen Bound 2, it has been optimized for large HD screens (Secret Exit says that it looks good on a 100" projector), with improved textures, lighting, and shaders. The Mac version also supports multi-touch for the laptop trackpad or the Magic Trackpad, so experienced Zen Bound-ers should feel right at home with this new, larger version.
