In brief, the video demonstrates part of an independently-produced proof of concept project, and features a custom "Blue Spheres" level to demonstrate potential additions to the game-

-Green Spheres are two-hit spheres that can't be readily used in combos
-Pink Spheres teleport the player to another randomly-selected Pink Sphere
