Arrow colours etc?

[mghvk]

Hello!

Ive never played DDR or any dance machine before, so the relevance of the arrow colours may be something to do with FFR's dance machine brethren... but still, i'll ask anyway.

Some songs have multicoloured arrows (red, blue, yellow etc) whereas others contain nothing but blue arrows. Is there any significant purpose for the multicoloured arrows in some songs or should I just ignore them?

Also... really... are songs like Flight of the Bumblebee actually possible to FC? I can survive the song... but seriously, thats the most incredible feat ive pulled off in the 200-odd games ive played. Other than that I can only FC standard level songs and the occasional tricky.

Thanks.
