Hello! Maybe a stupid question, but I didn't understand the rule "The game must be able to load on Windows". Is it possible to make a Web game that will work on a PC without a download file, or will the game be estimated by download file?
Not a stupid question at all! You can make a web game, but you still need to provide a Windows-compatible download for judging. While additional platforms (like web or Mac) are welcome, the judges will only guarantee evaluation of the Windows version of your game.
