It wasn't on my Atari ST.
I really should have another crack at this. I've almost but not quite completed it; throughout the game you come across a number of tools as collectable objects (I think there's 14 in total; something similar anyway). At the end of the game you need one at random, but if you've missed picking one up, the game will randomly ask you for the one you've missed. Swine of a thing.
I'd like to think that I remember most of it. Certainly the early parts I could do in my sleep. Don't forget to feed the dog.
