Final Notes
When you've made all the necessary changes, you can re-zip your game folder and it's ready to upload to Steam! Bear in mind though, that the steps will need to be repeated for every platform you plan on publishing to - so if you want your game to run on Mac, Windows32, and Windows 64 for example, you should have three different versions ready.
Remember if you've changed the extension on your package.nw file, to change it back to .nw before publishing!
Finally, when it comes to testing your achievements etc. Greenworks requires Steam to be running in the background with a logged-in user to work. Also, if the app ID is not valid and installed, Greenworks won't work either.
If you want to watch a video from a Construct user who's published to Steam, YouTube has you covered, like this one for example.
Good luck with publishing to Steam!
