Thanks! Could you tell me how? Whenever I try to upload the windows executable, it replaces the file that gets embedded.
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.
