Fun idea, I always enjoy the whole survive with a limited amount of power type of game.
However, there are some clipping especially with the walls and fireplace. And the control menus aren't up for long enough to see what to do. I had to restart the game multiple times to see the instructions for how to clean the window and survive the night (for example). You should put the controls in settings.
The pros are the overall ambiance of the game. I was scared to leave the cabins, even at daytime. The footsteps really add to the whole spooky feel, at any second something could come running up to you and I love that feeling. The idea was generally cool and I was excited to see what would happen with his sister.
