The game's genre is clearly leaning more into the mystery and horror side. I especially love how eerie the game is and makes the player feel, like when the text is full of stutters and makes it seem like you're possessed and then snaps back to normal. An incredible delivery of horror in only just text format!
I agree, even the use of the changing the text speed does a lot to give a sense of unease / instability. I really love the sense of isolation in this work, purely from the text alone. I do think this is a concept worth finishing, or at least seeing some sort of conclusion eventually.
edit: I read the description and I don't know if you necessarily need items (though I think multiple choices leading to different endings would be interesting). I enjoyed the concept in itself and even if it's just a linear exploration of what it means to pursue light (hanging onto feelings) or letting go.
