STYLE: Clean 2D stickman animation with thin confident lines, no shading, no textures, no dialogue, no subtitles. Only speed lines, smear frames, impact rings, skid marks, and small sharp red blood accents on the hardest hits. Brutal, stylish, fluid, old-school internet stick-fight energy. MAIN CHARACTER: A solid black stickman martial artist with a tied kung-fu headband on his forehead, long headband tails trailing during motion. He is calm, precise, deadly, and never stops moving downward through the stairwell. His style blends kung fu, taekwondo kicks, elbows, redirects, wall steps, stair-assisted counters, and fast chained combos. ENVIRONMENT: A simple cross-section building interior drawn with thin black lines on a white background. Visible stairs, landings, doors, and corridors. The hero keeps descending floor by floor while fighting nonstop. Defeated enemies may remain as colored bodies on upper floors. ENEMIES: Each floor has a new colored stickman with a unique style. Purple - acrobatic aerial fighter, spinning kicks, wall rebounds. Red - boxer, heavy hooks, pressure combos. Blue - evasive counter-fighter, sweeps, slips, intercept strikes. Green - long-range kicker, whipping legs, lunging attacks. Yellow - grappler, clinch, tackle, slam attempts. Orange - berserker striker, rushing elbows and shoulder crashes. Final enemy - dark elite mirror-opponent with a thin white outline, calm and technical. CAMERA: Mostly side-view wide shots showing clear stair geometry. Fast but readable cuts, occasional whip pan, short push-in, crash emphasis. TIMELINE: 0:00-0:02 - Wide shot. Hero runs down from the top floor. Purple enemy flips in from above.

Hero slides down the handrail and lands on the next floor. Red enemy bursts through a door throwing hooks. Hero slips, parries, drives a knee into the ribs, then finishes with a spinning back kick. Small red fleck on impact. 0:04-0:06 - Whip pan down. Blue enemy attacks low on the stairs with a sweep. Hero hops over it, runs two steps along the wall, drops back with an elbow, redirects Blue's counter, and throws Blue over the rail. 0:06-0:08 - Smash cut. Green enemy attacks with long-range kicks on the landing. Hero ducks a whip kick, traps the leg, stomps the support knee, then launches a rising kick that sends Green backward through the doorway. 0:08-0:10 - Cut on impact. Yellow enemy ambushes from the corner and grabs the hero in a clinch. Hero drives short elbows, steps on the rail, flips over the grip, and slams Yellow face-first onto the stairs. 0:10-0:12 - Hard whip down. Orange enemy charges upward like a battering ram. They clash on the staircase in a savage rapid combo: block, elbow, knee, duck, kick, shove, rail-bounce, straight punch, spinning elbow, stomp, cross, final chest kick. Orange crashes into the w
