Gain max run speed using a runway in the neighboring room, and jump through the door. With this amount of speed, it is possible to make it across without any tanks.

Entrance condition:

{
  "comeInBlueSpinning": {
    "unusableTiles": 1,
    "minExtraRunSpeed": "$7.0"
  }
}

Requires:

{
  "notable": "Reverse Speedball"
}
"canTrickyJump"
"canSpeedball"
{
  "heatFrames": 370
}

Gain high run speed using a runway in the neighboring room, and jump through the door. With a precisely timed unmorph and a buffered shot to open the door, it is possible to just barely make it through with no tanks. After unmorphing, walk instead of running, to avoid bonking the door.

Entrance condition:

{
  "comeInBlueSpinning": {
    "unusableTiles": 1,
    "minExtraRunSpeed": "$6.5"
  }
}

Requires:

{
  "notable": "Reverse Speedball"
}
"canInsaneJump"
"canSpeedball"
{
  "heatFrames": 392
}

Break the speed blocks by jumping over the gap with blue speed and continuing through the room with a speedball. If entering with low speed, unmorph after killing the last Pirate at the bottom of the sloped section, in order to run and gain more speed for the rest of the room.

Entrance condition:

{
  "comeInGettingBlueSpeed": {
    "length": 1,
    "openEnd": 0,
    "minExtraRunSpeed": "$2.4"
  }
}

Requires:

{
  "notable": "Reverse Speedball"
}
"canSpeedball"
{
  "heatFrames": 570
}

Clears obstacles: A

Dev note: A run speed of $2.3 can also work but with greater difficulty. FIXME: add strats for cross-room spring ball bounce (with momentum or temp blue) and Space Jump
