Very cool! I'm a fan of maze themed games, partly just because you never know what you'll find. I won't comment on the system itself, since I'm not familiar with SGS, but I do like the way the counter interacts with the prompts.
Favourite details: "Is there anything else with the arrow?" is a great leading question that opens a lot of interesting narrative directions. I also really like 18's "what makes it safe?" (super evocative) and 19's "this section is artificial," which tells a story all in itself.
