How to play Floors 3D
- Press Start, then allow the microphone if the browser asks.
- The climber sinks by himself. Hum a low note and he walks left; whistle or sing a high note and he walks right.
- Steer him through the gaps in each floor. Spiked floors and the rising spike ceiling end the round.
- Arrow keys, or holding the left or right half of the picture, also steer. You have 30 seconds.
You see the shaft from the side, all in blocks. Floors 3D listens for pitch in the page. The audio never leaves your device and nothing is recorded.
