I had that once for download on TBZP. The many moons ago that it was.
For those who are interested, there's a flaw in my design

So I'm having to do a redesign. Well, at least I can just copy and paste the content, so hopefully, when I worked out something that does work, it'll be up...
Edit: Having re-read your post, no I do not have a walkthrough for this version. You got a map there, that should help somewhat. Walkthroughs spoil games, I think. Eventually, you'll get where you need to go.
Edit: Actually, walkthroughs are good and enhance games in many ways, especially modern ones where it would be impossible to find every single hidden item, i.e. Gold Skulltulas in Zelda: Ocarina of Time or the Knights of the Round Summon in FFVII.
