Okay, so I made a game and tried exporting it for the first time. First I tried to export it in the desktop app, but of course you need to buy the full version of the program to do that (which is fine with me and I will consider buying it soon... But I tried to export it in html, and it made the file and everything, but I didn't know how to play it. I tried opening every file it made, but it wouldn't run the game. When I opened a file named, "Index" it opened chrome and said that I needed to upload the game first. What does this mean, and how can I play my game?
