Church skips are used to move diagonally throughout tiles in the old church. position your character at the corner of a tile and dash diagonally around a corner, or diagonally into tile that would otherwise take 2.

The Jesus Strat is used to get from the cave to the hospital in record time. Go right of the cave until you reach the end of the mountains, walk along the side of them next to the water until you see a lighter shade of blue, that part is walkable. Load in the black tiles to be able to safely cross the water, and you'll end up on the left of the hospital.

After clearing all 3 dungeons and going to the monolith, head to the right of the city, under the overpass and through a sliver you can walk through in the cars "blocking" the edge of the map. walk off the edge and wait 3 seconds. The game automatically sends your camera back to camp, finishing the game.
