How to play Flap

Press Start and allow the microphone. A pixel moth flies toward brick gaps. Hold a sound and it rises. Go quiet and it falls. Pass through a gap to score. Touch a wall, the top, or the ground and the round ends. You have 30 seconds.

Flap measures volume in the page. It does not send audio to a speech service and it does not keep a recording. The moth and the gates are drawn here.
