You have to take all files and zip them, after that you can upload it!
how do you zip a file
For example WinRar or 7Zip
Watch this: https://www.youtube.com/watch?v=fNLpZVNDQqc
should the unity platform be webgl
if you want the game to be playable in browser than yes
if I want it to be dowloadable
than export it as win and zip it like in the vid
It's Done now and its zipped ;
if that don't work I'll give up;
Its working great job man!
Thank god and thanks to you and the community
