Is it unable to download because of the file or because of a certain device? This is my first ever upload so I don't know how to. Thank you for commenting tho.
Did you actually hit a button to export when you made the file? Or did you just upload the game file you were editing. It looks like just an editing file. There should be an option to export it as a specific type of file, such as .exe or .html, which will allow the game to be played without needing to open it in game maker.
