By the way, the current posted method for #30 is...really, really unnecessarily difficult. On the backside of the building are a couple of stacked barrels in between two overhangs. Jump on them, then jump away from the building diagonally to land on either of the overhangs. From there jump onto the cliffside, then run along that to the roof which is an easy jump. The only jump you can really fail on this is jumping from barrels -> overhang.
