This game feels like a road trip. You've absolutely nailed the theme; you build the relationship between Rai and Claire well, and by leaving Rai with their own thoughts for stretches of time you really help the player feel immersed in their world & experiences. Some of the conversations can feel kind of stilted, but I can completely understand how a short-form visual novel can result in that. It can be hard to strike the right balance of world-building & genuine dialogue. At no point did I feel particularly scared - I think the photo feature serves to dispel some of the horror, where a lot of the psychological comes from uncertainty of threat & danger, the photos seem to show actual reality (monster-free) and we're given no reason to doubt that.
This game feels warm, and it feels personal. Thanks for making this game.
