> FWIW, I don't see a 10 second delay. I see a delay of roughly 2.5 seconds (Firefox; Chrome is a bit slower), followed by a Unity splash screen (which you can disable once you buy a license). But the delay obviously depends on the speed of the user's machine and network.

I don't know if it's barely downloading. Looking at the Dev tools, it looks like it downloads assets, then takes a good while to parse them.

> Even if some systems, like physics, can be removed if not used, Unity is still a full-blown 3D game engine. It can of course also do 2D, but it'll almost inevitably have a higher overhead than a dedicated 2D WebGL engine.

So, there's no way to not "load" the 3D component or other components besides physics, or is there?

Unity will automatically exclude the things that can be excluded. See "Strip Engine Code" at https://docs.unity3d.com/Manual/webgl-building.html

This only goes so far. E.g. Unity doesn't have a separate 2D renderer, so your 2D game will use the 3D renderer. (But obviously, a 2D game won't include any 3D materials etc.)
