Your use of sound (and sometimes the lack-of) is excellent! It contributes to an already tense atmosphere, one that definitely worked on me. I did have an issue with the game freezing after interacting with the toilet but it worked the 3rd time, just have to interact with the correct one. I'm hopping on Steam right now to add it to the wishlist! Wish you the best of luck with your game.
Thanks for making games!
