This is a strong game with excellent narration and very clever plotting. 
 
Don't be put off trying it by the critical reviews. Bad IF rarely receives actual reviews, and I suspect most authors criticize parts of this piece because it is very, very good. 
 
I am unaware of anything else Harrison has written, which is a shame. I do hope that this author creates more interactive fiction at some point. 
 
The good: 
 > An original story with an interesting twist. 
 > Many well-written characters and dialogue. 
 > An alternate ending which you are incredibly unlikely to get on a first play-through. 
 > Freedom and choice in the first half, although, with many constraints. 
 
The less-good: 
 > Linear story (This isn't a contradiction--the story is linear, even railroading you into actions and choices, but you have a surprising degree of freedom in how you make those actions, which allows for a very fun early game on your second play) 
 > An alternate ending which you receive no clues or suggestions to achieve. I suspect most if not all players would not realize that an alternate was possible if not for the author informing them. 
 > Several minor typos. 
 > The occasional "purple prose" example.  
 > Some strange action/verb choices. 
 > No follow-up work from Harrison, which is a shame. 
 
All in all, I enjoyed this game immensely. Very fun and very well-written.
