i'm terribly upset about this game. most people play by using there them and pushing on the string. for some reason, i learned by playing with my thumb and index finger together, like i'm holding a pick, and flicking the string. i got really good and I and II and it all worked. but they changed something with III and for some reason it just doesn't work that way. so i have to pretty much learn how to play all over again doing the thumb thing. fuck.
