Ok. Just to confirm from my friend. Switching challenges erases progress. I'm not sure how you tell when you're done with a challenge, but I know for the first one I did receive an achievement. So.. I guess you can tell that way Also. The overshell.if you press start at most any time, that brings up the overshell with instrument specific options. Finally. To play keyboards on the guitar, you apparently have to unlock it by five starring a ton of songs. This is something I don't agree with.
