I am a slow reader. Despite this, I was able to play through the game in about 20 minutes. "Play" is a generous term. The attractively rendered HTML pages contain a couple of hyperlinks each that serve to take you to the next room or an item description.
The writing is good, the descriptions evocative, the grammar correct (at least, I didn't spot any errors). But at no point was I frightened, nor did I feel that my actions had any bearing on the progress of the story. It felt like a pick-a-path adventure where all the choices lead to the same page.
In fairness, I didn't play through more than once, so it's possible that clicking links in a different order leads to a different ending.
