After I got the key in the bathroom I didn't what to do. Also, after I went upstairs, I was stuck on the stairs and couldn't come down to continue the game. But the environment and the atmosphere created were great :)
Thank you for playing the game, btw in the attic there's a trigger on the side that moves the story forward. I guess the trigger wasn't big enaugh, or maybe it wasn't intuitive to go there.
