Really liked the art style and the vibe! I’d like to see a version of this with fleshed out and further puzzles.
I agree with a previous commenter that the text is hard to read in places, because there’s light text on a light image or background (often with similar colors!). It also wasn’t clear to me that I couldn’t turn around until I had talked to the passenger twice (which is intentional, right?)–maybe you could indicate that the passenger hasn’t finished talking somehow?
