Continuing with the web-based stories, I tried Howling Dogs, which is written with Twine/TiddlyWiki. I can comment on the medium before the spoiler cut, and leave story-specific details to the side for a moment.
The presentation feels very natural. The typography is modern and clear, and links are obvious. Navigation works just like you’d expect, including the browser back button. I was surprised how well the story conveyed a sense of different rooms and of objects in the current location. The story makes good use of several locations that become familiar, which is a welcome anchor when the story otherwise rockets off into surreal spaces. The author has put to good use the ability of this system to remember prior player actions and to alter text in successive accesses. Because of this, the story does not come across as a flat hypertext document, but a narrative that progresses in time.
Havoc! Now for some spoilers.
