HEy im not particualarly a newbie but im still not that good :P I can do some difficult songs but im now stuck on Very difficult.
I mean i can do some of the bits, but when it comes to places where there's arrows everywhere, i just can't do it and resort to button mashing. They just go up so fast i dunno which is next. Any tips for that? I tried shrinking my screen and stuff but it doesn't help. I been practicing the same song for like 10 days now and have only managed to get passed the certain hard bit like 5 times. It just confuses me to a point where i just give up
