I can't find one of the 2 keys for the door with the two locks...searched everywhere..help!

Did you "give the sacrifice" ? (Put meat / and skull for secret on the tile behind the bars)

I need to put a skull as well?

I did the meat part.
I got the key for that part...it's the other key I can't find.

Yeah, destroyed them all :( Really can't find it nowhere. I scanned the whole level, tile by tile, nothing :/

This must of taken me an hour to figure out. I kept trying to find a way to open the door. I already figured something needed to go on the pallet, but I didn't think I could just place it there. I tryed to throw stuff and it bounced back ARGH now I know.

Were you able to get past that point?

One key is obtained via the sacrifice (it doesn't have to be meat for just key ,anything will do). The second key is in the large room with numerous spiders and eggs. The key is in the alcove in the upper left corner behind spider eggs (opposite to entry doors).
