A half tile is considered unusable, in order to be able to quickly spin jump forward after gaining the shinecharge.

Requires:

"Gravity"
{
  "canShineCharge": {
    "usedTiles": 15,
    "openEnd": 1
  }
}
"canShinechargeMovementComplex"
{
  "shinespark": {
    "frames": 28,
    "excessFrames": 0
  }
}

Exit condition:

{
  "leaveWithSpark": {
    "position": "top"
  }
}

Dev note: FIXME: If Morph or X-Ray is available, an extra half tile of runway could be gained by standing up inside the last tile of the platform.
