You think you got away. You really hope they don't know how to use a ladder.
There's 4 passageways in the floor, each one has a ladder.
You could try listening to the sounds coming from the holes.
THE NOTE
If you go down either hole, something interesting will happen. I already got 2 of these things figured out, the rest I need to improvise. And ONE of these holes will lead to a GRAND awesome thing.
I'll leave it to you to choose though.
