Oh that's weird. Are you sure it was the basic link and not the one with count down mode?
The one I shared in the parent is for the New Year's countdown: https://tetris-time.koenvangilst.nl/?mode=countdown&to=2026-...
The basic link should show the current time, even at high speeds: https://tetris-time.koenvangilst.nl/?speed=10
Oh wait, I just tested it on a higher speed (20) and I see what you mean. It's drawing over the existing Tetrominoes! I'm going to max the speed at 10.
