Entrance condition:

{
  "comeInWithGMode": {
    "mode": "any",
    "morphed": false
  }
}

Requires:

{
  "or": [
    "HiJump",
    "canWalljump",
    "SpaceJump",
    "canIBJ",
    "canSpringBallJumpMidAir",
    "h_crouchJumpDownGrab"
  ]
}

Exit condition:

{
  "leaveWithGMode": {
    "morphed": false
  }
}

Dev note: There could be an artificial morph IBJ option, but that would just bypass a crouch jump + down grab requirement.
