Fantasycore? Hobbitcore? Gobblincore? I'm not sure what fanbase these games falls under, but its my vibe.
If you make more of these in the future, It would cool if players could learn the names of the flora and fauna in the images. Maybe you start with blank journal and an entry appears when you visit each new scene. You can easily upload the photos to an app like iNaturalist to ID them. (But mushrooms are a bit tricky to ID from photos.)
