If you don't know what CPS is, it means Clicks per Second. I have coded a machine (button) that will test you're clicking speed. All you have to do is press the green flag and click the button as fast as you can. When the gong sounds the game will stop counting clicks. Then it will tell you your CPS along with a comment on how well you did. Please leave your CPS in the comments! My best is 11.9 (I don't do jittering that much)
Just your standard CPS tester, not much to it. Please let me know if you have any suggestions or ideas to make it better! Maybe I'll add a leaderboard sometime...
