After the first 4 clanks, try to press space to the clanks. After enough presses, click on the cat to hear how off your rhythm is. Negative means early, while positive means late.
I made this because I was playing a rhythm game based on dreams, and my inputs kept being off. There was a calibration option, but I wasn't sure how many milliseconds my inputs were off by on average, so I made this to find out. After 75 presses, I got... 0.02 or 20 milliseconds. :/
