Basic Attack
A two-part advancing attack uses Motion Warping to track the player, creating reliable close pressure without demanding perfect spacing from the boss.

Core Mechanic
The fight is built around converting defense into offense through Momentum. A perfect dodge opens a brief buffed attack window; dealing damage during that window builds the Momentum meter, and filling the meter unlocks a powerful finisher.
This creates a clear player rhythm: read the boss, dodge at the last moment, stay aggressive during the buff window, and cash out accumulated Momentum. Instead of escaping pressure, the player is rewarded for remaining close and turning the boss’s aggression into their own advantage.
Experience Goal
This demo is centered on one core combat language: DODGE. I wanted the player to survive pressure by reading attack anticipation and using precise timing to turn defense into a counterattack.
I wanted the player to feel hunted, but never helpless. A successful dodge does more than avoid damage: it transfers initiative from the boss to the player, creating a continuous exchange of pressure, evasion, and retaliation.
Boss Design
Design Goal
The boss’s core design keyword is fast. Its speed and aggression are not simply there to increase difficulty; they amplify the demo’s central combat language—DODGE. The boss creates frequent, immediate threats, while precise dodging gives the player a way to answer that pressure. These two ideas are complementary parts of the same combat loop.
Behavior Logic
I designed the boss to make decisions from distance, attack availability, and the player’s current action. At long and mid range, it selects an appropriate attack or closes the gap. At close range, it can pressure, hold position, retreat, or counter. This keeps the boss proactive while preventing a single response from dominating every situation.
Boss Moveset
I divided the boss’s skills into interruptible and uninterruptible attacks to control the exchange of initiative. Interruptible moves give the player moments of local control; uninterruptible moves force a defensive response and let the boss reclaim the pace. Each skill also answers a specific range or player behavior.
Six-Hit Combo
A clear warning precedes three ground slashes and three aerial spinning strikes. Its commitment creates sustained pressure while preserving readable counterplay.
Sliding Rush
A high-speed slide immediately chains into an aerial combo, preventing the player from escaping pressure simply by creating distance.
Retreat Attack
The boss jumps back to reset spacing, then fires a projectile from the air. It turns retreat into active space control instead of a passive reset.
Retreat Variant
Instead of firing a projectile, the boss immediately teleports back in with a basic attack, punishing players who automatically chase the retreat.
Vanish Thrust
The boss disappears briefly, then reappears beside the player with an immediate thrust, creating a compact reaction test and rhythm change.
Character Design
Perfect Dodge and Momentum
The character’s core mechanic is the perfect dodge. Dodging within 0.2 seconds before impact grants a three-second buff window with increased movement and attack speed. During that window, damaging the boss builds Momentum.
Filling the Momentum meter unlocks one powerful, uninterruptible attack. If the player stops damaging the boss and does not trigger another perfect dodge, Momentum gradually decays. This turns precise defense into a temporary offensive opportunity and encourages the player to stay close, take risks, and capitalize on the advantage they earned.
