Bugs Are Part of the Horror
Of course, there is another reason watching development is entertaining.
Bugs.
Glorious, beautiful, ridiculous bugs.
Every horror developer dreams of creating an intimidating creature that makes players scream.
Unfortunately, development occasionally produces something that makes players scream for entirely different reasons.
The terrifying monster suddenly walks backwards.
A character's head rotates 180 degrees.
A door opens into another dimension.
A chair develops the ability to levitate.
The player falls through the floor and discovers the secret underground civilization that apparently wasn't supposed to exist.
And somewhere, the developer quietly mutters:
"I'll fix that later."
This is one of the joys of development footage.
You get to see the ugly, unfinished stage that players normally never experience.
And sometimes those mistakes are absolutely hilarious.
