Very fun/cool UI. It's surprisingly reminiscent of Metro, err, Windows 8 Style UI. You could wrap an iPhone in some clumsy metal/plastic Windows phone wrapper from a year ago and you'd have no idea what OS was powering this.

I haven't tried the game yet but at first sight, it seems to be heavily inspired by Meego Harmattan / Symbian Belle - a beautifully designed UI (at least in its Meego implementation) that unfortunately never went anywhere due to Nokia killing both Meego and Symbian before it was even released.
