How? Is there even an option like that? If yes, wont it still break on mobiles?
Nope if you make it work with touch screen and yes it is possible (itch.io supports uploading HTML games for play directly in the browser. In order for your game to function it must be implemented using web technologies such as HTML, JavaScript, and CSS. Many modern game engines support exporting to HTML & Javascript, which will allow your players to run your game directly in their browser without separate downloads or installs)
