Run from left to right on the dry platform to gain a shinecharge. Then fall off and spark to the left to break the speed blocks.

Requires:

{
  "canShineCharge": {
    "usedTiles": 32,
    "openEnd": 1
  }
}
"canShinechargeMovement"
"canHorizontalShinespark"
{
  "shinespark": {
    "frames": 72,
    "excessFrames": 10
  }
}

Clears obstacles: A

Dev note: Doable without a short charge, since there are 32 tiles (plus one open end) to charge it.
