Finished Easy & Hard, so thought I'd try Normal... except - the rooms with the Gold & Silver blocks - nothing works.  And pulling the levers in one room does not change the blocks in the other room...

Almost forgot - the room to the right, where you have the cute little guy to help - the blocks don't match, so you can't use the ladder, not going up or down... and since there's no getting up to the top otherwise...

Since there's no real money there and no keys to get, I thought of just skipping it, but there's no way down except by the bat thingy, which can't be reached at all the way the levers work (none of the ones I pulled open the gray door).

Hey Brell - I had no problem controlling the lever-pulling troll, but since the blocks don't match up, how does one get up above?  Everytime I changed rooms, they went back to silver... I would have the troll change them to Gold, move to the previous room but they've be silver!  How does that help?
