Charge a shinespark below the Oums, near the bottom right door, quickly move through the morph tunnel and spark up to the top door. This is an alternative to wall jumping.

Requires:

"Morph"
"Gravity"
"canShinechargeMovementComplex"
"h_shinechargeMaxRunway"
{
  "or": [
    {
      "shinespark": {
        "frames": 39,
        "excessFrames": 4
      }
    },
    {
      "and": [
        "canMidairShinespark",
        {
          "shinespark": {
            "frames": 33,
            "excessFrames": 3
          }
        }
      ]
    }
  ]
}

Dev note: Jumping into a diagonal spark saves a little energy from both the jump and hitting the slightly lower ceiling by the door.
