Demo project does not work on fresh pull

[sampenguin]

Running the demo on a clean install will load Spanish as the default language and nothing happens when you push the play button on the Loading screen. This is because there is now a RemoteConfigGO object, and it's default values do not work if no RemoteConfig values are fetched.

After fixing this in my own install, the documentation needs to be updated with the following steps to run the project:

• You must link the project to a project config in the Unity game services dashboard, and at a minimum configure the following key value pairs in the RemoteConfig service linked to it:

1. "Language" as string (default value should be "English")
2. "Season" as string (default value should be "Default")
3. "CharacterSize" as float (default value should be 1)
4. "CharacterSpeed" as float (default value should be 5)
