Thank you, this was somewhat helpful but then again after I build my game, what files do I need to include in the zip file exactly and on the other hand, how would I go about it if I chose the github option?
I think it's best to put in a zip the build of the game on itch.io, and on github the source code only. Obviously in the post on itch.io you will have to put a link to github. On Github it's possible to have a page and put the build, but I don't know how to do it yet.
