I started this thread because last week I played FLC for the third time, I ended the game with 31 keys!!!!!!!!! When I reached the "lost bay" I had 29 silver keys, and I took the 30th there (it supposed to be the 29th)....so I could open the chest that needs 30 silver keys immediatly. Then when I gave all the keys to the demon door I took the last key (what was supposed to be the 30th) in the fishing spot near the door..... (it was my 31th silver key)
The next thing I did was to google in internet for a walkthrough and look at the silver keys locate section.....All the guides says that there are only 30 keys.....and then I realized that one of those 30 keys was the one in the fishing spot on lake in "Headman´s Hill" when you fall down with thunder!!!!!! I didn´t fight with thunder instead!!!!!! so I did not take that key....
So, I wonder if there are 32 silver keys in total (or even more).
Now I am playing FLC again and I am writing down all the silver keys locations to see if I am able to find those keys again.....
