Come in with a shinecharge, and perform a moonfall off the ledge. While falling, fire a shot at the door and immediately activate the shinespark wind-up, to horizontally spark through the door.

Entrance condition:

"comeInShinecharged": {}

Requires:

{"shineChargeFrames": 140},
{"notable": "Main Shaft Moonfall Spark"},
"canMoonfall",
"canShinechargeMovementTricky",
{"shinespark": {"frames": 12, "excessFrames": 0}}

Exit condition:

"leaveWithSpark": {}

Unlocks doors:

{"types": ["super"], "requires": []},
{"types": ["missiles", "powerbomb"], "requires": ["never"]}

Dev note: This is more difficult than the one in the Etecoon Shaft since there is not time to activate the spark after landing. Instead it must be activated mid-air while falling at high speed. With the vanilla door connection, this strat doesn't seem possible, due to just barely not having enough shinecharge frames.
