It is a Quest 3
Thanks, that helps! We tested it on a Quest 3 and saw the same thing there: almost 30 seconds of sound with no picture on the first start. In demo 0.3 a loading screen comes up within a few seconds and the sound waits until the game is ready. Loading still takes about half a minute on the Quest 3, so making that faster is next. Demo 0.3 will be on this page soon.
I waited and the game did start on my Quest 3.
It needs more guidance about what to do. Just saying 'Throttle' doesn't say a value to set it to.
Eventually I got moving and ran through some trees near the airport before managing to take off.
Where do I need to go? Is there a place to reach?
I decided to follow the blue dot and went down the valley between the mountains . I was doing fine until I switched on the auto-pilot who flew us into the mountain!
