Back in the summer (you know when it was warm), Liege was on Kickstarter with a Vita stretch goal. All of that got funded and the Coda Games team, led by John Rhee are now hard at work on building the game. A recent update on the KS page shows off their approach to the game's art (final version below, check the post for the creation process).
There's also a sneak listen for some of the soundtrack, and some discussion of how Unity helps them handle the 2D and 3D graphics translation and interaction. An interesting glimpse into the development processes.
