So from what I hear they really screwed this port up. They force a bunch of gimmicky stylus controls on you, like instead of just timing the gas button to get a boost at the start of the race, you have to rub the screen a bunch, or much worse; for the hovercraft you have to blow in the mic. They replaced the coin challenges with this mode where you fly around the coarse wherever you want in first person with stylus controls just popping balloons. Boss fights are now just drawing lines and spinning a wheel on the touch screen.
