wow. Loved this, so visually clean and simple - IMO this is the best looking game of the lot. Simple mechanics - easy to learn, tough to master. I'll admit that I'm not great at rhythm games that don't involve lightsabers, so once I hit stage two I was a little bit lost - but that doesn't detract from the experience at all.
Loved the extra juice - the red flash on the bar at the bottom when you miss, and the parallax & camshake. One thing I would love though is for the green squares to flash white when you successfully hit one! An incredibly minor nitpick, but a nitpick nonetheless ;)
