Walk the Geemer up the slope, killing any wavers on the way. Once the Geemer reaches the top of the second slope walk left to move it off screen. Go back down the slope to gain enough runway and build a shinecharge up the slope. Jump over the Geemer and perform a slopespark on the slope close to the door.

Requires:

"canUseFlashSuitInitialSpark"
"h_shinechargeMaxRunway"
{
  "shineChargeFrames": 125
}
{
  "enemyDamage": {
    "enemy": "Geemer (blue)",
    "type": "contact",
    "hits": 1
  }
}
"canSlopeSpark"
{
  "shinespark": {
    "frames": 9
  }
}

Exit condition:

{
  "leaveWithSpark": {
    "position": "bottom"
  }
}

Dev note: Holding dash to run into the Geemer can also be used, the dashing method causes Samus to land faster, which should make the position of Samus on the slope less precise.
