While its visuals suggest cutesy entertainment for teething toddlers, later levels become mind-bendingly tricky. Just as there were few that didn't struggle with PaRappa's chicken in the kitchen, many will find even the first level of Um Jammer a chore. Sometimes it seems like you've strummed your little heart out, hitting every symbol perfectly, only to fail at the end for no obvious reason.

Indeed, the freestyle mode is the key to quick success; a method of random button bashing in between scripted notes to up the quality of your performance. Complementing this are the alternative axe effects (wah wah, reverb, etc) that you win after completing each level. By the end of the game, true freedom of musical expression should be yours.

Sadly, it won't take you long to unlock all of Lammy's delights, for although tricky at first, it's the kind of game that, once the basics are learned, will be zipped through in a couple of days. A surprise cameo from PaRappa himself adds longevity, but his raps are no match for Lammy's brand of tuneful rock.

Musically, you can't fault it. From funk to soft rock and thrash metal, almost every musical palate is catered for. It may be a tad too easy in single player, but the team and battle modes mean that Um Jammer Lammy should remain a party favourite, as well as an entertaining solo diversion for months to come.
