On Newgrounds(2nd official version) there is no way to tell about your misses. but the version you play actually is harder for me to play because I use "S D J K" instead of "D F J K"
The Newgrounds doesn't have the Accuracy or the Misses Counter. it's not even in the options(unless you have to sign up I think) and you are free to do whatever controls you like
Ya see, the thing is, im on a school chromebook, my regular chromebook is being used by my mom for tv because it broke... and my school is REALLY strict
