Nice!

I think the purpose of the dropdown on the error screen could be clearer. Perhaps a text line above the dropdown?

On the navigation, I felt it was far too fast. I could see some larger sketches needing that speed, but perhaps it could be modified by the shift key?

Also , the vertical camera adjustment felt back to front to how I would expect moving a camera around.

I'm one of those gamers who immediately turns on "Invert Y axis" on every game. Now I can inflict my preference on the world!

Yeah. No. I guess I'll change it. :-(

I've improved this to the point where I think it's ready for review.

Just realised - I overlooked this comment and I haven't changed it. I'll update this now.

What is the relationship between this and Monoscopic mode? Can this replace the monoscopic build?

This is intentionally separate from monoscopic mode. It might eventually replace it but at the moment it's very different:

a) Much easier to use. WASD+mouse navigation. Monoscopic is kinda weird.
b) No editing or UI - it simply allows you to load a sketch and fly around it.

Ok, so it's a potential replacement, but currently feature limited. That helps. That also explains why when I tried it, many moons ago, on Mac it looked just like Monoscopic. (do we want to try for a view-only mode on Mac, or would that require spending way too much time getting it to build a VR-capable-but-not-really-so-that-it-fails-every-time build?)

It shouldn't do. It should initially look like this:

I'd definitely like this to run on MacOS, iOS and Android. The work @mikeskydev is doing should enable both an iOS and MacOS build without errors.

For platforms without a hardware keyboard I'll have to work on the controls a bit. (I'd also like to get a build working on Android Cardboard VR)

[mikeage]

I don't think we'll get there, though, because the only Mac build we have is monoscopic. We don't have an OpenXR or SteamVR build for Mac.

[mikeskydev]

A mac build could run without including any of the XR plugins, which should trigger the same conditions as not having a headset plugged in
