I got the Plat and had a lot of fun doing it. The high point for me was figuring out
the Golden Path. I drew my own map too, which is always fun.
Everything leading up to
the Secret Treasure was fun too but I had one frustrating moment where I had to look up and confirm whether I was on the right path or not. And this was of course whether I was supposed to
translate the runes of the hidden message using the cipher at the back end of the manual. There's nothing quite like that in the rest of the game so I wanted to double check before going through the hassle. Seemed like overkill for what turns out to be such a small, not that crucial part of the game. Other than that, immensely satisfying puzzle/adventure game.
