I always leave the build to the end. This time I decided to do it early. After lots of messing about in hyperspace... er... installing Visual Studio, I got a successful Windows build to work. Then discovered I could simply upgraed Burst and it works without VS! Doh! Oh well.

Have now successfully built for Windows & Android (with Burst) and without any changes it still compiles for WebGL!!! Nice. I think I can also compile to MacOS and Linux but not tried those yet -- might leave to run while I have lunch... sadly no way to test MacOS (unless someone volutneers) and Linux would require booting up one of my older machines (where I used to run with it all the time).

Unity cross-platform is no myth -- it really is the biz!
