Velocity Clash

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a playable browser-based 3D arena fighting game titled “Velocity Clash.” Use a third-person perspective with a dynamic perspective camera that continuously frames the midpoint between the player and rival; pull the camera farther back when fighters separate, raise/bring it closer during an ultimate, and add subtle camera shake on impacts. The environment is a dark futuristic circular platform called Skyrail Nexus: a broad charcoal/navy cylindrical base, a dark inner circular fighting surface, a bright cyan-blue glowing ring around the edge, and evenly spaced pale-blue metallic rail posts around the perimeter. Place a sparse skyline of tall, nearly black-blue rectangular towers in the distant fog. Light the scene with cool blue ambient/rim lighting and a strong warm key light, with soft shadows, glossy/emissive accents, and a deep blue-black gradient sky/fog.

Make the match a fixed 1v1 battle between two original mascot-like humanoid fighters. The player is Azure Rush, positioned initially on the left, with a bright blue body, cyan accents and glow, white gloves, white shoes, a rounded cartoon head, muzzle, large white eyes with dark pupils, small pointed ears, and several swept-back cone-like quills. The rival is Crimson Shade, initially on the right and facing the player, using the same stylized proportions and construction but with deep burgundy body parts, pink-red accents/glow, and dark shoes. Give both fighters a small colored circular aura/ring at their feet. Animate their arms and legs procedurally while running, make them face the opponent, and visually pose them during attacks, jumping, hurt reactions, and dashing.

The core goal is to reduce the rival’s health to zero in a fast arena duel. Both fighters have 100 health, a regenerating Boost resource, and a regenerating Ultimate meter. Movement is physics-like and velocity-based: the player moves freely across the circular arena with WASD (also support arrow keys), jumps with Space, and dashes with Shift while consuming Boost. Normal movement is about 6.2 speed and dash movement about 9.8; preserve momentum enough that attack damage increases with the attacker’s current velocity. Keep fighters within the arena boundary and bounce/slow them when they reach the edge. Jump with an upward impulse, apply gravity, land on the platform, and show a landing impact.

Provide four attacks: Light on J, Heavy on K, Special on L, and Ultimate on U. Light is a short, quick close-range strike; Heavy is slower, stronger, and has a somewhat longer reach; Special is a larger purple-accented attack that costs 20 Boost; Ultimate is a powerful long-range finisher that requires a full 100 Ultimate meter, consumes the meter, grants temporary super armor, briefly slows time, flashes the screen, and displays a message that the fighter unleashed a dimensional finisher. Attack hit windows should be timed within the attack animations and use distance/facing checks. On hit, deal base damage plus a bonus based on attacker velocity, apply hit stun, launch/knock the target backward and upward, build the attacker’s meter, increment the combo, and create readable feedback: colored impact rings, expanding ground shockwaves, flying particles, brief hit flashes, sound beeps, and impact camera shake. Let attacks also damage nearby breakable stage props; heavier/special/ultimate attacks should be especially capable of destroying them.

Scatter seven destructible props around the arena at roughly radius 7.5, alternating between pale-blue futuristic pillars and orange/tan crates. A pillar consists of a faceted base, tall cylindrical shaft, and glowing white-blue diamond/octagonal cap; a crate is a large tan cube with dark brown brace details. Props have hit points, break when depleted, explode into airborne chunks with gravity and spin, emit a shockwave and sound, and are removed from the stage. Breaking props should help build the fighter’s meter through the normal combat feedback/rule messaging, but do not add other hazards or stages.

Implement a rival AI for Crimson Shade rather than a second human player. It should chase the player when far away, dash toward the player at distance, strafe and switch strafe direction when close, dodge/space is not required for the AI, and probabilistically choose light/heavy attacks at close range, special attacks at mid range when it has enough Boost, and occasional Ultimate attacks when its meter is full. The AI should use the same movement, attack, hit, meter, Boost, stun, knockback, and KO systems as the player.

Build a glassy, responsive HUD over the game. At the top left show “AZURE RUSH” and “PLAYER” with three horizontal bars: health, Ultimate meter, and Boost. At the top right show “CRIMSON SHADE” and “RIVAL AI” with matching health, meter, and Boost bars. Center the title “Velocity Clash” and a contextual status line: initially show the keyboard controls; during play explain that velocity boosts damage, warn when Boost is low, and announce when Ultimate is ready. At the bottom show a Moves card listing Light J, Heavy K, Special L, Ultimate U, Jump Space, and Dash Shift; show “Combo x0” (updating during a combo) and “Skyrail Nexus · Break props for meter.” Display temporary stacked messages such as the arena loaded message, the velocity-damage rule, prop/super-meter reminder, resource warnings, and attack announcements. When either fighter reaches zero health, stop the match, show a large centered gold “KNOCKOUT” banner, announce the winner, and change the status to indicate refreshing to rematch. Include touch/mobile controls at smaller screen sizes: a directional pad with up/left/down/right buttons and action buttons for JUMP, DASH, LIGHT, HEAVY, SPECIAL, and ULT. Use dark translucent panels, cyan/red/gold/magenta/violet gradient bars, white typography, subtle blur, and responsive layouts; hide the desktop control cards and show the touch controls on narrow screens.
