Usually I missed a circle when playing maps, but I am not really have good vision and reaction to find out where the spot I've hit. 
And not only for a miss circle, but the hit one also I can see where I really "hit at", this is very useful that players can improve their performance.
Here have some suggestions:
--in skin there is a pic called particlexxx.png, this pic show/spurt out when click the right circle, but not at the right spot cursor hit(only spurt at the middle of circle), it is better that alter this pic to show at right spot.
--create a new click effect to show this idea.
Thanks for your reading.
