I actually did find an English translated Korean indie VN on Stove that doesn't seem to be available anywhere else, a free, very short horror game called "No Gaze."

Worth checking out if that's your jam! The story is pretty typical as these "students disappearing in a creepy school at night" things go, but it does some neat things with art and the interface. The fact that the video feed on your phone of your friend walking around the school is actually animated with the camera moving around the hallway seems like such a simple detail, but I found it really surprising and effective.
Ending spoilers in next post, because I am kinda confused there and I'd love if someone else played this and could discuss it with me!
