Hey! Thanks for playing! Glad you enjoyed!
I believe all doors when they open/close make a sound as well.
You play as someone who's walking into the facility to explore and finds the voice logs and everything as if it's after the creepypasta story, so as of now you're playing as yourself going in to explore.
The game goes through the creepypasta's story but there may be more in the future as well, thanks for the support!
