Not that I had any subsequent tasks at hand, but thanks. Few things I'd consider: 1. Make it to not stop when the time's out. New users will wonder if a minute passed and see 0:00, happy. Regular users will know the trick and will learn to spend as much time as they need around a minute, instead of feeling interrupted. Some will be angry, they failed anyway. 2. Make the "dot" smaller and blurry to avoid sharp halo. 3. Fade-in unintrusive "vvv" under 0:00 to suggest scrolling down for a random short advice/info. What was expected, how to deal next time, and so on. Educational and praising component. 4. Dark mode for those who can't browser extensions. 5. Click on a circle is probably barely discoverable due to the nature of the process. I'd push it down to #3.
