Old Game

I doubt you’ll be able to help, but something has been bugging me for ages. When I was a kid I was given an adventure game for Xmas. It was my first one and I had no idea what to do. I figured out some of the basics, but gave up on it. I’ve never got over it beating me, and if I could find a copy I can emulate I’d have a proper go at it. The trouble is I don’t know the name.

All I can remember was that it was for the Commodore 64/128. It had pictures, if you can call them that. I think I remember a beach, and a computer/machine that required a code (which I could never find). Unless I’ve mixed it up with another game, I’m pretty sure that you went to Madame Tussauds, or somewhere similar. Does that ring a bell with anyone? All of this would have been within the first few locations. I never got very far with it at all.

I know its a long shot, but I thought I’d ask anyway, lol.

Maybe this?
