Jump and diagonally spark up left to land on the upper platform. The Powamps can be used as a reference of when to spark, however they move up and down. Spark when samus is a few tiles left of the first Powamp, or almost half way between the first two with HiJump.

Requires:

{
  "useFlashSuit": {}
}
{
  "or": [
    {
      "shinespark": {
        "frames": 34,
        "excessFrames": 5
      }
    },
    {
      "and": [
        "HiJump",
        {
          "shinespark": {
            "frames": 31,
            "excessFrames": 5
          }
        }
      ]
    }
  ]
}

Dev note: Because this jump is somewhat blind, the excess frames are not very tight.
