Dive into the acid to the left of the first floating platform to quickly sink to the bottom of the room. It is possible to jump directly over the pirate at the bottom of the ramp directly to the gap between platforms. Falling in this way will land between the platforms at the bottom of the room.

Requires:

{
  "notable": "Reverse Acid Dive"
}
{
  "obstaclesNotCleared": [
    "A"
  ]
}
"canSuitlessLavaDive"
{
  "or": [
    "SpaceJump",
    "canTrickyJump",
    {
      "and": [
        "canLateralMidAirMorph",
        "canCarefulJump"
      ]
    },
    {
      "and": [
        "ScrewAttack",
        "canCarefulJump"
      ]
    },
    {
      "and": [
        "h_heatProof",
        {
          "enemyKill": {
            "enemies": [
              [
                "Yellow Space Pirate (standing)"
              ]
            ]
          }
        },
        "canCarefulJump"
      ]
    }
  ]
}
{
  "heatFrames": 320
}
{
  "acidFrames": 195
}

Dev note: It is faster to fall all the way to the bottom and then jump onto the platform to the left, than to morph/unmorph to reset fall speed to reach it directly.
