Entrance condition:

{
  "comeInSpaceJumping": {
    "speedBooster": true,
    "minTiles": 18.4375
  }
}

Requires:

"canCrossRoomJumpIntoWater"
"canMomentumConservingTurnaround"

Dev note: This is on a spike in the speed graph, but higher tile counts work too. FIXME: With 7 tiles (extra run speed $2.0 or $2.1) or 11 tiles (extra run speed between $2.C and $3.1), it is possible to make it onto the floor below the floating platform; there's currently no node there, but with a flash suit it would be possible to spark up from there.
