So, I think this is what various keys open, but I'm still having some problems:1) Spade Keys. One opens the Spade Tower. Don't know about the other one yet.
2) Chrome Keys. They open the royal rooms on Level 2. But there is one door up there (south of the King's Room) that they don't open, and I jammed the lock. Should I try an Iron or a Copper Key?
3) Iron Keys. Anything on Level 1, but also at least one door in Basement 1 (the door into the Jailor's Key room).
4) Copper Keys. Basement Level 1 (except aforementioned door).
5) Jailor's Key. Don't know yet.
6) Gold Key. Don't know yet.
Does anyone have more information, especially on 1-4? MTIA.
