>a bit of a hallway section with an arena surrounded by pits and a glass hallway after that room
You mean this area? I see the item behind the glass, and I see it's the same area of which I can visit the lower level, but even with 3 jumps in my moveset I can't reach high enough from down there. From this room is a laser room with a hull upgrade I don't know how to reach, and another pit hallway with gold statues encased in glass and a bunch of enemies, where the door to the vertical dash upgrade is.
