I feel an immense, overarching dread right off the bat.
The art is lovely and very human, yet stylized very well; it creates that dread you're probably aiming for. The lack of color only helps, however I'm fairly certain that it'd give a lot more credence to the story if certain actions — like the Player almost dozing off — were actually visual rather than solely textual with the player's face comprising the only image seen.
The music assisted in making the experience unsettling as well! Are these Jackie Originals:tm:?
The choices, while there're only two of them, felt pretty logical and straightforward. I didn't really feel railroaded onto one path, even though I was.
I expect the story to gain a pretty damn eclectic sort of air, one of dread and smelling strongly of stale honey. I also expect colors, few of them, maybe colors that I've never seen before. Mom won't answer the phone, but she will be on Zoom instead.
I like it! The style is pretty slick, though I can confidently say that I want more.
