Oh, I see! I could only finish the first two levels by luck earlier, now the first four, but unfortunately I already forgot which direction is which sound, I've been always bad at "Simon says" :D
Oh, so that's what "shift" is for! But... it does not do anything in my browser :( I tried in both Firefox and Chrome on Windows 11. Maybe adding the tones to the movements would help as that way the player should only repeat the pattern.
