I appreciated the story, the metaphors were well thought.
But I don't feel like you took advantage of the the video game medium, which is interractivity.
I'm a huge fan of story games (idk if it's because I'm a writer or because I have no skill) but I feel like if you can have the same experience by doing little to nothing, there's a problem.
Even walking sim like What remains of Edit Finch or The Beginner's Guide take advantage of the interractivity, you don't just walk, you explore, you look around, even starting cutscenes if your action.
Here, the text is already there, the only point of moving is to move further, and I don't feel like this would be any different to press a "next" button.
