I won't speak to the technical side of the game since I'm not a developer, but I really don't appreciate the use of AI voices. It's not hard to find quality actors, and the rise in AI is only going to make it harder for quality talent to find work. Let's not perpetuate the use of it, please. With regards to story and narrative devices this has potential and you've got a great concept on your hands. It's a nice offshoot of the "moon's haunted" meme. Gameplay wise it'd be cool to see this expanded to more than just walking back and forth.
