Flowmotion

Flowmotion (フリーフローアクション) is a gameplay mechanic that appears in Kingdom Hearts 3D: Dream Drop Distance. It allows Sora and Riku to traverse their surrounding environments with great ease when they interact with certain environmental elements. Using Flowmotion, Sora and Riku can jump off of walls, grind rails, leap great heights, and dynamically attack opponents.

When Sora and Riku use Flowmotion, they are enveloped in a violet aura, and they are sometimes accompanied by two orbiting lights of the same color, that trail light behind them.

The full set of Flowmotion commands are automatically equipped to Sora and Riku's command decks after Sora meets Neku in Traverse Town.

Story
When Sora awakens in Traverse Town, Neku can be seen using Flowmotion over the rooftops, using a Wall Kick off the side of a particularly tall building. After the two of them meet, Neku heads for the Second District, executing a Pole Spin, Rail Slide, and Super Jump along the way.

In the Grid, when Rinzler attacks Riku and Sam Flynn on the Throneship, Riku uses a Wall Kick to knock Rinzler off of the ship's bridge.

Back in Traverse Town, Riku corners the Spellican in the Third District by Wall Kicking and Super Sliding in front of it, forcing it to switch to Sora's Side.

When Sora confronts the Spellican in Symphony of Sorcery, it leads him on a chase through a starry sky, as he Rail Slides along a sparkling trail.

Mechanics
Flowmotion is activated by pressing to Dodge Roll or Air Slide into a wall or other interactive object, or by landing on certain environmental features, such as rails or fountains. Sora or Riku will perform a context-sensitive action, such as briefly sticking to and jumping off of a wall or spinning around a pole after Air Sliding into it.

Once a Flowmotion is activated, it can be chained together with additional actions. The player may press to use a Burst of Speed to travel long distances or transition to another Flowmotion-compatible surface,  to perform a Super Jump that boosts the user to a great height, or  to use a Flowmotion Attack (フリーフローアタック), which depends on the Flowmotion action the player is using.
