Entrance condition:

{
  "comeInWithGrappleTeleport": {
    "blockPositions": [
      [
        5,
        3
      ],
      [
        7,
        2
      ]
    ]
  }
}

Requires:

"h_ShaktoolSymmetricFlag"

Clears obstacles: f_ShaktoolDoneDigging

Dev note: Grapple teleporting crosses the room, so it will set the flag 'f_ShaktoolDoneDigging', assuming that the game is modified to treat the room symmetrically with how the flag gets set.
