Drift sparks and some boosts are removed when moving straight up or straight down in the air
Boosts that are removed when the player is not moving are removed when the player is not moving horizontally while in the air, regardless of whether they are moving vertically. This causes drift sparks, stored sliptides, wavedashes, and voltage to be removed by interacting with certain object or setpieces such as dash rings which launch the player directly up or down.
