Tight movement is needed to enter with a shinecharge, carry it through the morph tunnel, and spark out the right door in time.

Entrance condition:

"comeInShinecharging": {
  "length": 2,
  "openEnd": 0
}

Requires:

"canMidAirMorph",
"canShinechargeMovementTricky",
{"shineChargeFrames": 175},
{"shinespark": {"frames": 7, "excessFrames": 0}}

Exit condition:

"leaveWithSpark": {
  "position": "bottom"
}

Unlocks doors:

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

Dev note: There doesn't appear to be enough time to spark out in a 'top' position.
