Challenging!
It has several different modes of play, time attack, challenge,puzzle and the newly introduced mission mode and each mode is fun in a different way. In time attack you must clear the blocks within a certain time, puzzle mode is very difficult in my opinion because you have to make pictures out of the blocks, it sounds easier then it is.
The music is really great, it has a few good songs on which seem to keep you in the swing of it. Lumines 2 has a licensed soundtrack so you will hear songs by popular artists aswell which is cool.
Gameplay: 7/10
Music: 9/10

If your expecting a game like tetris then you will be disappointed, this game is so much different but i would recommend it, its good for a quick go.
