Lure the Gamets to the top left door with Ice and Grapple or HiJump. First lure the Gamets vertically using the Kamer platform and Ice, which is much easier with HiJump disabled. Then freeze them again after they separate and are high enough to align with the door. With HiJump and another jump assist, jump to the left of the Gamets as they thaw and refreeze them a bit more to the left so that they will be on screen when Samus is on the left ledge. It is possible with HiJump and Ice alone, but much trickier. Use the Gamets as a platform or perform a running jump from the Kamer platform to get up to the left door.

Requires:

"canTrickyGMode"
"canTrickyUseFrozenEnemies"
{
  "or": [
    "Grapple",
    {
      "and": [
        "HiJump",
        {
          "or": [
            "SpeedBooster",
            "canWalljump",
            "canSpringBallJumpMidAir"
          ]
        }
      ]
    }
  ]
}

Exit condition:

{
  "leaveWithGModeSetup": {}
}

Dev note: This is possible with fewer requirements, but it is already pretty terrible.
