Love a brain-bender and I think I knew where to go, although I didn't quite make it either! My take was definitely similar to Colby in counting the corresponding number of items that reflect the drawing - be they candles, barrels, or bodies, in the basement. I found the text throughout the level as an abstraction of the player's state of mind and reaction to their predicament an amusing way to go about it without dialog or audio. I'll have to get my counter and see if I can delve in again and figure out how many damn bodies were down there...
