It’s been updated (20th anniversary) and remains as notoriously difficult as memory serves. It’s a standard text adventure (with a few linear graphics), but where your Level 9s offered po-faced responses and treated errors with incomprehension, this game tried to anticipate where you might go wrong and when you did, laugh at you.
