Starting from the door, use a 1-tap shortcharge to gain a shinecharge running to the right. Use the remaining runway to gain speed to clear the pits with a single jump, using Screw Attack to avoid Boyon damage. Then spark vertically or diagonally.

Requires:

"canShinechargeMovementComplex"
"canCarefulJump"
{
  "canShineCharge": {
    "usedTiles": 23,
    "openEnd": 2
  }
}
"ScrewAttack"
{
  "or": [
    {
      "shinespark": {
        "frames": 118,
        "excessFrames": 6
      }
    },
    {
      "and": [
        "HiJump",
        {
          "shinespark": {
            "frames": 113,
            "excessFrames": 6
          }
        }
      ]
    }
  ]
}

Dev note: There could be another tile if the door is open, but it shouldn't matter at this runway length with canCarefulJump.
