From the start, there are two ways to go, both very perilous. The first way is to jump on the fragment above the up thwump, jump to the left wall, and let the left thwump activate above you, then wallclimb and walljump into the main ruin. The other one is also hard: go right, past the up thwump, then jump and land on the ledge in-between the two mines, then jump into the main ruin. __NOEDITSECTION__
