Might have a lot of potential, but you need some kind of a showcases right at the start, highlighted to show what is possible. I clicked around and first worlds I saw were very basic. Maybe if users saw something incredible right at the start, they'd be motivated to be more creative

it looks beautiful

I am sceptical of these things however since they are a well worn path that so far has taken off only to a limited extent. In reality, you get bored very quickly in these environments, and it's impossible to implement impressive visual fidelity in worlds that users build themselves. Horizon Worlds is probably the marquee example of that. Am curious what the differentiating angle is here to previous efforts?

Free air, No head spins, nice wind, clean air vs fake ?

I wonder which is better...

You have an off-by-one frame rendering error; your camera is not synced with the player (tested on both MacOS and windows). I also got 10s hitching on load on a beefy windows rig -- might be missing some shader compiles on the loading screen.

You're probably optimizing for XR, but 99% of people will experience your app for the first time on a different platform, so it's worth fixing the desktop render path.
