Will give 7:43.37 a go

The congratulatory end sentence? I found it straightforward. The purpose of the game, as implied at the start, was to avoid having your soul sacrificed.
Very wisely designed game - it never overreaches and slows down. The most enjoyable isometric game I have played. I was always very fascinated by Fairlight and its manipulation of objects and by The Great Escape and its living NPCs, but for sheer playability, I prefer this one and the about-30-room size is just perfect.
A VIC-20 masterpiece for sure.
