Align with the right side of a wall or door then turn around and shinespark in order to avoid colliding with a slope.

Requires:

{
  "obstaclesCleared": [
    "A"
  ]
}
"canShinechargeMovementComplex"
"canHorizontalShinespark"
"h_shinechargeMaxRunway"
{
  "heatFrames": 335
}
{
  "shinespark": {
    "frames": 221
  }
}

Dev note: There is enough time to visit 3 and return to 2 before performing this strat with the shinespark. The obstacle being broken means Samus has run far enough to charge a shinespark.
