That's probably about right. I know there's more games like that as well, I remember seeing a horror game like that on youtube that I forget the name of.

Wikipedia just calls it an "adventure game". Feels like there must be a more specific name for the genre, but I don't know what it is.

Visual novel? "Walking simulator" (originally derogatory, but sometimes used descriptively now)?

Visual Novel does sound right, good call.

Walking simulator I've heard applied to a bunch of different kinds of games, unfortunately. Mostly RPGs.
