I realised I haven't updated lately . The map is complete, you can walk and do everything you need to do to get there. I have decided to make some small changes, for instance, if you travel south you will eventually be in the room you started in. I am closing off the map so that there will be a north/ south boundary. Also, there Are several points in the original when there is absolutely no hint as to what you need to do so I'm adding in more print statements. But otherwise I think that when the time comes, this "sierra" version will be released as a demo, it will be a complete game, the final release will be a redrawn extra puzzle affair. But that will take a really long time.
