Welp, you win, I'm too scared to play your game, haha!! I felt immediately unsettled and couldn't really convince myself to move anywhere beyond the living room/foyer/kitchen area; I did go up to the attic but then immediately went back down and completely "noped" out of the game, haha, sorry! It's effective, and I'm sure any further scares involved are even more so; maybe I'll ask my partner to play it and let me know what happens... or I'll watch this youtube link from the other comment.
Something that would help me personally get through it would be a brightness option, my screen seems overall too dark even when my system brightness is all the way up, so it was also very difficult for me to see anything in game which wasn't directly in the light; I typically turn in game brightness way up on darker games that allow for the option.
