It starts as an interactive movie with narrative progression. Interesting.
As the others said, a little better onboarding would help - with a help page or a settings page with the controls. You give the hint "Press F" permanently so in the beginning I thought F was the Interaction key. It was just the flashlight. One of the annoying, flickering ones, only to be found in horror games. Reading the description outside of the game, I entered the house. Good use of cutscenes here.
By the way, you grass/flowers around the house looked like anti-tank obstacles, especially in the dark. I'm quite sure they are not as you intended. I did not find the breaker box either but I was nearly every room, even the attic. Quite effective spooky mood.
The well-lighted green equipment at the van (which has no inner colliders) misleaded me at the beginning to think that the main place of the game were there, and that I should do something with it. Just turn the light down there and a little up at the house, so you can lead the player better where she or he should go. ;-)
