I quite enjoy the game, and how you use the jam theme.
I think reposition/reinstantiate the ghost when we press a new button was a smart decision, other wise they always come to us from door side which would makes it less fun and more challenging.
I love how intuitive the game is. Almost every house have a button for room light, and that button is on the wall. Also, using one of the most universal fears, fear of darkness, is another great move. I did understand what I need to do after my first attempt to switch-off my room's light.
A small note on audio, you could set your audio source's spatial blend setting to zero (2D) to make background music consistent in every point of house.
