I feel it's necessary to talk about the game because several people have shown difficulty with it.

Sparky is primarily their main issue. They told me that the door noises are too low and that the sound does not always play.

Unlike the others, Sparky's mechanics were not intended to be based on sounds. I tried making the door silent, but it felt odd, so I never removed it, instead, I made noise very very low.

Basically don't wait for the noise, you have to frequently look back.
