M&M Kart rated, Mario Kart better watch it's back.

...and try not to run into the wall from laughing too hard.

IGN review score below.

 

3.5	Presentation The five M&M's characters are the most appealing part of the package, but that's not saying much. Generic alternative characters fill in the rest of the ranks.
3.0	Graphics Fair representations of the M&M's characters are brought down by a horrible framerate, pop-up, and a graphical "wash" effect that plagues each background.
2.0	Sound Terribly repetitive. "Approaching sound barrier!" is repeated constantly, again and again, by a far-too-cheerful announcer. Sorry, buddy. It's not that fast.
2.5	Gameplay Cramped, claustrophobic level design means you'll often get stopped or stuck. The core gameplay is boring and too straightforward. No items, shortcuts, etc.
2.0	Lasting Appeal Endless chocolate coin collection ultimately allows you to unlock unappealing extra vehicles. The challenge is minimal, even on the hard difficulty setting.
2.5 Terrible	OVERALL (out of 10 / not an average)
