Not bad at all though maybe a just a tad too quiet. And opening the safe was very confusing mainly because of the lack of indication of what number the player was putting in, later I understood that I simply had to turn it a specific amount of times but since that's rarely how safe combinations work, I was quite confused. Other than that, pretty spooky. I think it could have been scarier if the game wasn't so quiet but it is quite good the way it is now. Good job overall devs!
