So... yeah. Didn't make a map in a while. Decided to try out new triggers which were released recently by Eric Gurt.

Basic description:
You're in a jail cell and you're about to be executed... Fortunately, there's a hole in the ceiling wall which can completely change your destiny...
To get trough the starting section:
Jump into the hole above wall above door so the guard doesn't see you
Fall down when he goes into your cell and close the door
EDIT: Updated the map a little, enemies that walk can spot you if you're too close.
