I think that this game has a really good concept, and is executed well, but the ending is definitely shocking for no reason what so ever. I think it would have been cooler if the game never "ended" and instead you kept cycling through checking the mail and going back upstairs, with nobody in the apartment. This would amplify the fear that comes from isolation, and in my opinion be a much more original and saddening ending. Still good work making horror without the need of jumpscares. :)
