The note puzzles were interesting, although I died the first time because I kept wandering around at the beginning hahaha.
And about the cover, I honestly don’t think it looks that much like AI-generated. It feels more like the person who made it doesn’t have full control over things like perspective—for example, the window and wall perspective are very uneven. They probably have a lot more experience drawing human figures than backgrounds. From my personal point of view, it doesn’t look like AI.
