I was torn on the timing difference showing up, so I do appreciate that feedback! I tried to lighten that distraction a bit by hiding this when you got the timing right, but I think I had gotten a bit too good at it during all the development runs and should have hidden this for everything beneath 0.3s or something.
As for the rating: Rate it as you like, I never assumed this would get high ratings. My main goal was to give people a little break and that seems to have worked out! If there's just one person out there who will continue to use this exercise in their daily lives, I'm happy.
