Intense game, much more speedy, great shortcuts and requires much more skill. Papus pyramid is pretty cool, when your going down a hill just before it gets bumpy you take a left by boosting onto a platform and then boosting back onto back onto the track to get to the shortcut on the side where there are a few item box things and its much quicker (spped boosts too?)
and then theres loads of other simple shortcuts like on a particular ice level where you bump over a wall and turn at the same time instead of driving all the way round.
Better than MK any day. well, almost anyday.
