This can be improved on. Try filling the instruments, instead of only the outlines, this'll make the area you can click on bigger. If you want to keep this style, just change the colour to alpha and then to zero, that'll make them invisible.
I do beg to differ wit that, driven2theedge. Why don't you upload a game, let's see how your first try goes?
Anyway, thanks to everybody who gives construcive criticism.
Also, when commenting with low scores, spelling does make you look less like a jackass.
