I really love the aesthetic / top-down approach you have with this game, and there's definitely a mood that can be expanded upon, with a person in solitude, trying to sort out their thoughts about what it means to connect with someone on a journal. There's a lot of exploration of the narrator that can be expanded upon this for sure.
One question I have is: how do you imagine expanding upon this form of storytelling? Not to say that it needs to extensive, but I do imagine that being able to explore a couple of entries / days of this diary would be enough to grasp this character we're peering into (and actively writing).
