Your thread has to contain the Release tag. This way, the user has clear knowledge, that the game is downloadable. This also applies to unfinished/beta/demo versions of your games (as long as you provide a download link).

Start with the title of your game and main credits (developer, graphics, level makers)

Include couple of pictures to show off your work.

Briefly explain what your game is about: What theme it follows? how many levels are there? How difficult is it?

If you want to include changelogs, it's preferable if you keep them outside your OP and include as either thread replies and/or something like github gist (with all appropriately linked in your OP)

Your download link in the OP should always go to the latest version of your work.

Hope this helps
Cheers!
