Duality
Marble fight videos that end in a slow-mo knockout
Drop two marbles into a sealed arena for a pure 1v1, or build a larger free-for-all when available for your account, with five lives each. The spike ball arms whoever grabs it, hearts heal, shields soak one blow, and the final hit triggers a slow-motion replay with a winner fanfare. Then download the fight when your browser supports video export.
