Nothing is explained clearly. The character moves slowly, in a seeming abyss; the expanse just makes it more apparent how bleak things are. The one NPC I met was incomprehensible, because the key that I was supposed to press to open my inventory did nothing...if I was even pressing the right one. I have no idea, because I couldn't see it clearly; I couldn't make heads or tails of whether that was a J, an L, whatever. And then I got stuck talking to them again.
Poor controls, no apparent direction, no way of telling what's what.
