Been trying to upload my first unity game, The tutorials said to change it to .zip so I did with WinRar, and made sure it said .zip at the end. But it still doesn't work. Itch.io just keeps saying: " 

There was a problem showing your project

You've configured this page to show a unity game but you haven't uploaded the appropriate file!

Upload a file or change the type of this page on the edit game page. " 

Can someone please help me xd 

That it says ".zip" at the end doesn't mean it is a ZIP archive. Can you open it as a folder using Windows Explorer? I.e. not back in WinRAR. The latter has a pair of radio buttons that let you pick the format when creating an archive; make sure you select the right one. Better yet, just do it straight from Windows, it's a right-click away.
