Well, that doesn't exist. But "Journey to the Centre of the Earth" does! I know, I am dumb and didn't even think of it: my mind was stuck with "Mission" instead of "Journey". Too much studying, definitely :P

I know about the book, I just was doubting that it could be the original title of the game, as the version I played was pirated and sold at the newsagent... looks like the pirates weren't ashamed to use the original title, though :)

Thanks again, I am happy now. I suggest trying it, it's not that bad after all: the multi-item interface is quite original for the C64, the gameplay is smooth and well balanced. And the music is devilish, it will haunt my mind for a while :)
