In Kingdom Hearts 3D: Dream Drop Distance, the ability that lets characters wall-run and leap off walls is Flowmotion.
Flowmotion is a movement system designed to make traversal faster and more acrobatic. Sora and Riku can use environmental objects to bounce from walls, grind along rails, and spin around poles. These actions can also feed into rapid attacks, allowing movement and combat to flow together.
The system gives Dream Drop Distance a more dynamic feel than earlier Kingdom Hearts games. Instead of moving through worlds only by ordinary running and jumping, players can use the architecture of each area to build momentum and reach distant platforms or enemies.
Flowmotion is sometimes confused with Free Flow, a related development term and system concept associated with the game. Glide is a separate aerial movement ability, while Parkour is not the official name of the mechanic. The canonical in-game term for this wall-bouncing and environmental movement system is Flowmotion.
