Depending on Samus' exact Energy and velocity, it is possible to have one frame where she could end over unavoidable spikes. Entering with a spark at the top of the transition will prevent this.

Entrance condition:

{
  "comeInWithSpark": {}
}

Requires:

{
  "shinespark": {
    "frames": 146,
    "excessFrames": 60
  }
}

Dev note: FIXME: There is one frame where ending the spark early puts Samus over spikes with no avoiding them, unless entering the room at top of door. Which frame is determined by actual shinesparkFrames and shinespark velocity.
