Duael Designs LLC and Roamular LLC report that their first iPhone title has been approved by Apple and is now available for download in the iTunes App Store. Their game, Ro ($1.99), is an original puzzler that charges players with reconstructing an image by rotating a series of rings.
The solutions won't come easy, though - each twist of a ring will also turn one or several of the surrounding rings in response. The rules regarding which rings are connected change between levels, lending a significant amount of extra challenge to the core gameplay.
It all sounds pretty taxing, which is why Duael Designs has set up a website filled with tips and example solutions (complete with helpful Quicktime animations, even!). Ro features four levels of difficulty, each of which includes multiple puzzles to solve.
