dl/ing and installing =D

I think your ipod touch accelerometer got problem.

The one thing we noticed is that the default calibration is off, leading Crash to always veer left at the neutral point even when we started up the game with the phone on a desk. This means we needed to tilt the phone slightly to the right to go straight.

maybe you just not get use to it

no complain for me or my frie. lulz  how i wish can play online or LAN multiplayer mode

ya every ipod's accelerometer are different if you check with the app called (meetbubble)
mine is 2.3 to the left.
both of my friends are even worse which are 4.3 and 5.2 to the right
