i try to opload my game but there Comes error massage You've configured this page to show a html game but you haven't uploaded the appropriate file! bur i opload Release TemplateData index.html
A playable HTML game needs to be uploaded as a single ZIP archive with all the files in it, including index.html. If you just upload each file one by one, it won't work.
You'll need to give more details if people are to help you. After uploading the file, did you tick the checkbox labeled "this file will be played in the browser"? And two of those are directories, not files. Unity puts a lot of stuff in there. Make sure you packed everything.
