Before you package your game go into the Project Settings to set everything up.

In the Project section you can set a description of your game, tell it which map to start with (seen below), you can set a start movie, etc etc. For your first builds I’d recommend leaving most things at default. But you want to set up a starting map at least.

Under the Platforms Section you can setup your game’s icon and splash screen. It’s a little different for each platform so you need to add these things separate for each build.

Finally once you have everything set up, in the File menu go to Package Project, pick a directory and build away!

Lastly, while your project is building I recommend you view the output log at some point. You can watch it while it builds or check it out after. Look for red and yellow lines to see if there are any errors. Try to always correct any errors that might show up. If you don’t know what something means try Googling around. If you still can’t figure it out you can always try asking for help int he forums.

It’s always good to do a few development builds during the process of creating your game. This will enable you to test out how everything works as a final product. Sometimes things behave differently in the viewport or even when you test from the engine as a standalone game.

Your very final build can be a Shipping build so the file is as small as possible. Then zip it up and host it online somewhere. You can use dropbox or mega.co.nz for example, or if you want to share your game with the world http://www.itch.io. Share the link with some friends so they can help you test.
