The soundtrack is fantastic and really adds to the eerie feel the entire experience gives off! I also particularly liked the first time that you see the specter on the other side of the window, it really builds tension before stepping into the lighthouse and wondering what are you about to encounter. I think a nice little addition would be to have a counter of how many keys you have or when you used a key to open the door to give off a better sense of progression, especially on the first floor where backtracking is a bit more prevalent. Great entry overall!
