I've uploaded a new version of 'Seeker of Magic'. It's the same link and password as given in the first post. It incorporates all the changes suggested by my wonderful testers plus fixes for some other bugs that I found. There were some issues with the standard movement verbs that allowed you to (for example) use GO NORTH rather than N and bypass the obstacles related to the troll and darkness. This used to work, but there must have been some changes to Adventuron that caused it to break. I've had to completely redo this using barriers. I hope it works more reliably this time.
Enjoy. Bug reports and comments are more than welcome.
Now I'm ready to test other people's games. What fun!
