I like the choice of setting and suspense angle of your story. Though you need to remember to stay consistent in details, at the start when responding to the SOS call, the person on the other end is described as a female, but when you follow the distress call in your story and arrive, they are then described as a male, so it breaks the continuity, and makes you question if they are the same person or not. The other path, when noticing the figure in the shadows option is selected, I feel like I'm not sure exactly what the outcome of that is, like we're missing a passage, as after going down that rout you both arrive at the destination? A passage that explains what or who the figure in the shadows was would be nice, so it makes sense that you travel to the destination with them.
