I have noticed the way of how you made this game by a glance at the mechanics, for an example when you go to the downstairs you are able to hear the whisper sounds and when you go back neither 2 to 3 steps from that location you meet with the silence once again.Overall game was alright, i kinda surprised to the game's graphics compared to it's file size.Later i checked out the game files and found out UE4 game engine.I don't know you would want to take suggestions but just take a look.
-The hardest part of a game is absolutely developing a story.Pay attention to the term i just used."Developing" not "Writing", you need to read a lot and need to get information about the kind of game you are going to develop.
(I wanted to say the game's story is weak.)
-You are able to use audio so well.It is pretty scary to be honest and if you mix it with well written story it would be dope.Do not let silence to take over the audio.Put a chill&freaking ost for background and improve effects.
-Lights are not enough, i mean i get it that you need a dark atmosphere for game but just increase the lamp and other lightning tools's coverage area.You can just turn off them in a part of the story if you want to black out the player.
-I see that you haven't really designed the outside area of the house because you can see it by looking at the door in the kitchen.
-A few bugs that i realized :
1-)You are able to see behind the objects through camera angle by looking directly into the objects.
2-)The audio bug that i specified in the beginning.
3-)I just pressed E on curtain in the first room and got good ending somewhow tf.I don't know if it's a bug or not.
