Looking at the gameplay concept for Maestro! Green Groove – line running crossed with timed rhythm action – seems like a sure-fire hit. Sadly, this maestro is missing more than a few beats. The gameplay here is taken from a Nintendo DS game called Maestro! Jump in Music. Basically, Maestro! Green Groove involves watching a purple bird running across a highwire and using your finger to flick the wire up to make him jump, down to make him drop, strumming glowing strings as you pass them in rhythm and tapping bugs as they appear onscreen to defeat them, all following a set tempo.
