One of the best moments of game development is when we can finally build and test our game. To deploy a game in Unity to desktops (Windows, OSX, Linux) we must first open the build settings from “File/Build Settings” and select the platform.
To configure additional settings, we can select “Player Settings”, there is an option to add company and product name and set resolution. For testing purposes, I recommend Windowed mode, if you do not have the quit option implemented.
If you use the Filebase plugin and want to avoid deployment errors it is important to exclude the plugin before publishing.
Build your game, send it to your friends and test it, there is bound to be some room for improvement.
