Running does not help. This is most easily done with a late jump at the bottom of the slope. It is a bit less precise with an air ball or turning gravity suit back on and wall jumping on the platform at the end.

Requires:

"canGravityJump"
{
  "or": [
    "canTrickyJump",
    {
      "and": [
        "canLateralMidAirMorph",
        "canCarefulJump"
      ]
    }
  ]
}
