The music is not nearly as good as in the original.
We Love Katamari is great fun, but it's basically the same game as the original. Pretty much it's just a new set of levels: it's more like an "expansion pack" than a sequel. But if you reached the end of the first one and didn't want it to be over yet (that's me) then it's well worth buying.
