How to play Flap 3D

Press Start and allow the microphone. A block 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.

You look down the track from behind the moth. The gaps stand across the path and come toward you. Flap 3D measures volume in the page. It does not send audio to a speech service and it does not keep a recording.
