Update:
Not much has changed since my last update, except I've just tidied up a bit with the code generation. For those interested in giving it a whirl, I've uploaded a demo to the 'fan games' page.
At this point, all you can do is navigate the ego between rooms and see some objects & room descriptions. To get to all the rooms, teleporting will be necessary. Some single-verb words work ('look', 'scream', 'back', 'barf', 'say', a few others) - but they really don't do much. Oh, and all resources are currently 'external' to the game (pics, texts, views, etc) - not embedded into the resource.001 file.
I'm glad this is to a point where the community can have a look at what I've been putting together - I'd appreciate any feedback!
