If the right-side standing Pirate is still alive, let it walk towards the wall as far as possible from below. The available running space is just enough to jump up and wall jump the ledge by the door.

Requires:

"HiJump"
"canSpeedyJump"
"canWalljump"
{
  "or": [
    "canTrickyJump",
    {
      "obstaclesCleared": [
        "B"
      ]
    }
  ]
}

Dev note: This is also possible without going below and manipulating the camera, by standing on the slope and carefully jumping up and back.
