Great visuals and just overall atmosphere. I love the way the starting room is framed against the constant light of the lighthouse. I wasnt able to solve the lock puzzle but I think I did solve the first message? Not sure.
Only nitpick would be that the light changes color as its going through the office, which confused me for quite some time.
Edit: Actually, one more small thing, interacting with the computer felt a little awkward, the delays were too long between any actions
