Gauntlet

Q: hmm. I found merlin but he keeps asking me for clues..! and I always end
   up dying!! wtf?!
A: Well, there're eight clues (letters or numbers) you have to find in order
   to beat the game. If you miss a clue you have to go back to that clue's
   room and go get it.

Q: Right, so which rooms have the clues?
A: 16, 26, 46, 54, 66, 70, 81, and 90. The clues are the big ? symbols; you
   usually have to do odd things like opening locked chests and shooting or
   moving walls to get to them, kupo

Q: Why is it that the game refuses to give a password that takes me beyond
   room 79?
A: Because the game _hates_ you! You shouldn't have thrown it across the 
   room, you know!

Some passwords:

All of these start you with 1400-1500 points, ten keys, ten bombs and all
special abilities. The clue letters for these codes are: XRTW98Y7
