Thanks a bunch! Yes, this was very much a change in focus, with narrative being #1. I mirror your thoughts about game mechanics exactly - they were designed secondary to the story, so I can see how they feel a bit separated.
I agree that there isn't much in the way of branching possibilities - the idea that you may not be able to change your fate is part of the story, so many events have to happen. And yes, this adventure has certainly taught me text adventures are hard to code!
I hadn't even realised the release in America would be so fitting, so lucky me. Good luck for the secret ending! Don't forget there are hints in the usual place.
