A half tile is considered unusable, in order to avoid sliding into the wall and losing blue state.

Requires:

"Gravity"
{
  "canShineCharge": {
    "usedTiles": 15,
    "openEnd": 1
  }
}
"canLongChainTemporaryBlue"

Exit condition:

{
  "leaveWithTemporaryBlue": {}
}

Dev note: FIXME: An extra half tile of runway could be gained by standing up inside the last tile of the platform.
