For testing purposes only (since no map is currently developed), implement gamepad's vibration when player reaches borders of the down:

https://copilot.microsoft.com/shares/Y1a5qxeDgZuT3ELK2GXd1#:~:text=Vibration%20Support%20in%20Phaser%203

const pad = this.input.gamepad.getPad(0);
if (pad && pad.vibration && pad.vibration.playEffect) {
  pad.vibration.playEffect('dual-rumble', {
    startDelay: 0,
    duration: 200,
    weakMagnitude: 0.5,
    strongMagnitude: 1.0
  });
}

This uses core Phaser 3 support for game controllers, not the Merged Input Plugin (#22).

This is broken in Firefox and not supported at all in Safari, so can be tested in Edge and Chrome only.
