What engine are you using? Yeah I agree with others, WebGL is definitely the way to go for accessibility as players don't need to download anything, as long as they have a fairly modern browser. If your game is really laggy or resource-intensive, then you might have to go with Windows as it should be a little more optimized and may run better... But as long as you're not spawning hundreds of thousands of objects and stuff, this shouldn't be a reason to publish a PC only build
