OMC Neon Arena — Design Document

Concept

A top-down arcade survival shooter rendered on HTML5 canvas. The player controls a glowing "agent" orb, surviving endless waves of enemy "bugs." Built as a demo for oh-my-claudecode multi-agent orchestration — each subsystem was authored by a specialized teammate.

Tech Stack

No build step. Pure HTML + CSS + vanilla JS (ES modules).
Canvas 2D for rendering, Web Audio API for procedural SFX, localStorage for high-score persistence.
Served directly — open index.html in a browser or use a static server.

Gameplay

Controls: WASD/arrows move, mouse aim, click/space shoot, P pause.
Waves: Increasing enemy counts and speeds. Three enemy types: chaser (fast/weak), bruiser (slow/tanky), splitter (splits on death).
Scoring: Per-kill points scaled by wave. Combo multiplier when kills chain within 2s.
Death: Overlay with score, best score, restart.

Visual Language

Dark background with subtle grid.
Neon cyan/magenta/yellow palette; glow via shadowBlur.
Screen shake on hits, particles on explosions.

Task Decomposition

Scaffold + engine core (index.html, engine loop, input, entities).
Gameplay: player, enemies, bullets, waves, collisions.
UI/HUD: CSS theme, HUD overlay, menu/pause/game-over screens.
Audio + particles polish.
README with a "built with OMC" section.
