Completed Nightmare Mansion with 5 keys left unused

[rose]

Hi! I have played the mansion some. I have a vague memory that you can't manage to get to all rooms. My first try I went to the left initialy, got 9 secrets (there is 10) and got some spare keys, but I saw on the map that there were a lot of rooms I hadn't visit. Next time I first first went to the right. I haven't finished it yet.

My advise is that you play the mansion several times and try to find the best way to go.
