In the hangout, Ben stated that everyone should share screenshots of their work; and if they liked it, they might actually try your game. That would be impossible for me because I only posted the screenshots and some of the text without sharing the game. How would I give people access to my game as well?
Of course, you have to share a link to your game, too, if you want people to play it. What Ben means is that pictures are a better advertisement for your game than a line of text with a simple link.
Did this answer your question?
You would need to build to a webGL format and then zip the Index and two associated folders up.
You can then go to a site like itch.io (Our sharemygame site is currently not working) and there you can upload a game and change the file drop down to play in the browser.
If you need help with itch.io they have some good help files but give me a shout if you get really stuck
I currently have my main project hosted there atm
