Requires running a very precise distance of 12 tiles in the adjacent room and down grabbing onto the platform (extra run speed exactly $3.1).

Entrance condition:

{
  "comeInJumping": {
    "speedBooster": true,
    "minTiles": 12
  }
}

Requires:

"canCrossRoomJumpIntoWater"
"canMomentumConservingTurnaround"
"canTrickyDashJump"
"canDownGrab"

Dev note: FIXME: With 6.4375 tiles, it is possible to reach 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.
