This is a Ren'Py story that uses beautiful photography with a mostly linear story broken up by binary choices.
These binary choices always have an immediate effect, but I don't know if their influence lingers later on.
I love the type of story. It's almost like a romantic version of the Turn of the Screw. The hero is confused, foggy--possibly non-neurotypical. They have someone at home--sister? caretaker? spouse? And they encounter someone in the woods. But who and what are they?
The answers are never fully revealed, but gradually hinted at more and more. I found it effective.
