If needed, unmorph while passing through the blocks to break more than just the bottom one.

Entrance condition:

{
  "comeInSpeedballing": {
    "runway": {
      "length": 12,
      "openEnd": 0
    }
  }
}

Clears obstacles: A

Dev note: If we had a comeInWithSpeedball entrance condition, it should be used instead. This strat is for using a remote runway in the previous room to get the speedball; if the current runway were used then you could just run through with blue speed instead.
