Wall jump to the first platform then spark while standing, or spark from the right door - one tile lower than the Grapple blocks.

Requires:

"h_storedSpark",
{"or": [
  {"shinespark": {"frames": 121, "excessFrames": 4}},
  {"and": [
    "canPreciseWallJump",
    {"shinespark": {"frames": 110, "excessFrames": 4}}
  ]}
]}

Dev note: FIXME: Adding another node at the first platform would allow for cross room strats from the bottom right door.
