Name, window, language

Lives in: game.json

What the window is called, how large the picture is drawn, and which language the game starts in.

Title and version

{
  "title": "My Novel",
  "version": "1.0.0",
  "authors": ["Your Studio"]
}

Key	Effect
`title`	Name on the window, app file, and build folder
`version`	Your game’s version (used in build names)
`authors`	Credits; also the Windows app’s company field

To take the title from a translations file instead, use title_key — Translations.

"window": {
  "width": 1280,
  "height": 720
}

This is the base size your art and layouts are written for. The player scales the picture to whatever window or screen the reader uses.

"locale": "en"

That is the language the game opens in. Offering several languages in Settings is i18n — again Translations.

"icon": "icon.png"

A picture in the project folder, converted for each platform when you build. Details: Title, icon, splash.
