The first computer game I ever owned. I remember fondly playing it on a Commodore 64 on Christmas Day as my family were out playing the park across the road. Some quiet time on the day. 5¼” floppy disc and all.
I finished it a few years later with the help of a guide. I could never get through all the puzzles, and even on revisits, I still get stuck.
