Tap the diamond side · Crossed echo: wait
A solid diamond means tap that side; a crossed hollow echo means do nothing. Use the two buttons or ← and →. Three errors end a run. Clear a stage to unlock the next; replay to improve stars, streak and reaction time. Signals never require colour recognition. Settings and leaving the tab pause the timer. A hollow diamond is charging: wait until it becomes solid before tapping.
