So I thought that the halloween screen was pretty neat, but it only exist because the game is constantly updated and can be set to halloween in one version and changed back in following updates.
So would it be hard, and would it interest poeple, to had a check for the Date at launch and display a theme that is linked to the actual season (christmas, easter, first day of spring, any national holiday …) ? With I guess the different relevant season and associated screen being defined in json.
