@socketwench - I did this all from memory except for one puzzle, which is incredibly hard because you don't know what it is, or how to solve it and you can quickly put yourself in an unwinnable state.

I wouldn't say my runthrough is the best walkthrough (there's no text, all just me streaming the game from memory, but you will be able to beat all three games if you watch it.

I do have some maps I got back in the 80s, though. (this pic is probably not the best for playing, but I can scan them better if you want them).
