Thanks for the ideas!
1- I actually got a seamless version of the hum buzz sfx from one of my players, which I used in Backrooms: The Lore, but I guess I forgot to also change it for this game
2- I had to search for the Star Trek thing because I had no idea what you're talking about :)))) but this game doesn't have anything like that, it sort of reminds me of Cute Adblocker's ambient, but I'm pretty sure I didn't put it in Backrooms as well. Maybe the new hum effect will change your mind idk
3- I narrated that myself! And yep I did that on purpose, it gives to the atmosphere and many people fear my voice which helps with the horror element as well lol
