I just submitted a game for a gamejam and I want to have a downloadable executable alternative to the HTML embed so that people with a slow internet connection can properly enjoy my game.
Is this possible?
The normal thing is that you have a suffix in the name that indicates the system, for example.
game-html.zip
game-win.zip
You upload them as different files, the one that will be executed in the browser, you mark it that way and the other you indicate that it will be an executable for Windows, like the following image.
