It was one of my favourite games on our family's Acorn Archimedes in the early 1990s. I could play the first couple of screens on each of the ~40 themed level sets at age 7-8 or so, and sometimes the third screen, but then they became too difficult. I found it again at age 20 or so, and I could complete some of the level sets (8 screens in each), and I've gone back to it every 5 years or so, but there are still some puzzles I haven't solved.
