So I watched a number of the play-throughs on YouTube and spotted people were having difficulty knowing which person said what.
So I have added colours to the text using the Text Mesh Pro add on in Unity. Hopefully that will help.

Also I added depth of field using the Post Processing stack to add a creepier atmosphere.
I wrote all the camera movements myself which was hard, I am excited to see the Timeline and Cinemachine add-ons for Unity. They look so much easier to use to help get the atmosphere of the story across. I will use them for my next game, which will be a follow up the Classroom.
