There are several peripheral assets we need before we can publish our game. We will create a set of app icons, redesign the launch screen, and take screenshots for each device we support for the App Store previews.
Our app requires multiple sizes of our app icon to display correctly in the App Store and the various iOS devices we support. You can find a sample icon set in the provided assets bundle, in the Icon folder.
