Took some time to make. It was kinda confusing but i did (without a tutorial) it. took less than an hour, maybe 30-35 minutes. Just click the button until the timer is at 0. After the timer is at 0 the black square will appear and tell you your cps.
V1.1 - added a more advanced timer and fixed any bugs V1.12 -added a better wording system so you can see your CPS faster V1.14 I forgot what I did because I forgot to write this when I did V1.15-Added 1 sec cps updates (averages up at the end) Soon-V1.16-0.1 sec cps updates
