With Speed Booster equipped, run into the room using at least about 2 tiles of runway (at least $0.C extra run speed). If needed, perform two spring flings by pausing and unequipping Spring Ball, then pausing again and re-equipping it before bouncing on the first Grapple platform. Afterward, perform additional spring flings as needed to make it across the room, taking care to avoid the Powamp.
