Why is this game running like this (blue screen)

I played other games that are on UnityPlayer and they work fine but this football simulation won’t run as it should. It shows blue screen.

Any ideas?

Choices:

  1. There is an issue of some sort.
  2. It was designed that way, that blue is unity’s default background world space color.
  3. Something(perhaps an asset bundle) didn’t load and the scripting to load it was poor.
  4. Other
