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"]},
"canShinechargeMovementTricky",
"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.
