This is without doubt the best 2d platform game since the release of Super Mario World on the SNES18 years ago. Whilst many of today's games take graphical preference over playability NSMBW overwhelmingly spoils you with the latter and then some!
What starts out as a fairly straight forward challenge soon turns into an addictive level-by-level quest for survival. You'll breeze through some stages whilst whistling along to the quite brilliant background music whereas others will have you wondering why you even bothered to get out of bed and play the damn thing!!
The multi player mode can be good fun but should not be taken too seriously because it can at times be frustrating. However the single player mode is truely superb and worth the price alone.
