A new gameplay trailer has been released showing offf Tetsuya Mizuguchi's puzzle sequel, Lumines II, which drops onto PSP later this year.
For those who've missed out on the acclaimed music puzzler, it's a bit like playing Tetris on top of a blaring beatbox, and about as addictive as chain-smoking cigarettes laced with chocolate. We're sure you'll get the gist of it after watching this video - just don't play it on the train unless you want to end up missing your stop.
