Utterly charming - though those expecting new all new music will be disappointed, with the game presenting mostly altered versions of the tracks we all love.
Gameplay-wise this has had a revamp - the basic mechanic of tilt world /jump is there, but there are additional moves that are acquired as you go along. This means that there are areas of levels that are off limits until you replay with the requisite ability, giving an almost RPG feel to it.
There's also much more of a running story, with various cut-scenes introducing new characters (including a new locoroco!). The existing locoroco are given names and personalities, rounding out the entire game world.
Lovingly presented and, at times, nearly impossible to put down, this is a sequel that improves in almost every way while remaining just as charming and fun to play as the original.
