Ten small flourishes, all borrowed machinery

Kills stutter the world a touch more per streak; a massacre borrows the
boss's slow-mo; a boss death gets the transition's zoom punch. PERFECT
contact flashes a spark ring. The sidestep and every real bounce kick up
court-tinted dust. The net cord ripples where the ball clips it. The
landing ring contracts on time-to-touchdown. Hot rally balls drag three
fading ghosts. And every 8-15 seconds the floodlights stutter.
