I'm just curious if any of Windows10 users tried to use Desktop App Converter (https://developer.microsoft.com/en-us/windows/bridges/desktop), app from Microsoft that can convert Win32 apps/games to Universal Windows Platform - so such converted app/game can run on both win10 - desktop & phone versions, and can be published on Windows Store. It looks that should work with GLB made games, as there is also project ANGLE (https://github.com/Microsoft/angle) that can be used to port OpenGL ES commands to DirectX..
I don't have any device with Win10 so can't test it how it really works, but I will try to do some test with older Angle branch - for win8.1, just after I will deal with some build issues - just to many Win SDK packages and different VisualStudio version installed..
