🎯 Features

🕹️ Authentic VS Code Experience

• Pixel-Perfect UI: Lovingly recreated VS Code interface with activity bar, sidebar, editor tabs, terminal, and status bar
• Interactive Sidebars:
  • 📁 Explorer - View project stats and release progress
  • 🔍 Search - Browse enemy database with detailed info
  • 🌿 Git - Track your commit history through waves
  • 🐛 Debug - Monitor performance metrics, combos, and high score
  • 🧩 Extensions - Check your installed power-ups and upgrades
  • ⚙️ Settings - Tune movement sensitivity and toggle sound

⚔️ Intense Gameplay

• 9 Unique Enemy Types: From basic bugs 🪲 to merge conflicts ⚠️ to the terrifying MONOLITH boss
• Three-Phase Boss: Monolith opens with a reinforcement squad, then escalates its minion budget, tracking shots, spread fire, movement, and five-way final-phase burst across later releases
• Progressive Difficulty: Enemy health, speed, rewards, roster, and attacks scale across waves; ambient spawns use a smoother cadence with an on-screen cap while every clear grants modest baseline player growth
• Combo System: Combos decay one stack at a time, gain one stack per 5% Boss health dealt, and grant capped score, damage, fire-rate, and ultimate-charge bonuses
• Local High Score: Best run is saved to your browser and shown on the start screen and game-over screen
• Power-Ups:
  • ☕ Coffee - Speed boost
  • 🤖 GitHub Copilot - Temporary +1 weapon tier for 8 seconds
  • 🐳 Docker - Temporary shield
  • 🩹 Hotfix - Restore 30 HP

📦 Wave Upgrade System

After defeating each Boss, the player receives +5 max HP, +2 ammo, and +4% base damage, then chooses one smaller permanent enhancement:

Upgrade	Effect
⚡ Compiler Upgrade	TypeScript compiler +1 level (more projectiles)
❤️ Heap Expansion	Max HP +12 and restore 12 HP
📦 Buffer Overflow	Magazine size +5 and restore 5 ammo
⚙️ Fast GC	Reload 10% faster per stack (max 30%)
🔥 Overclock CPU	Fire 8% faster per stack (max 24%)

🎨 Polished Mechanics

• Advanced Weapon System:
  • Ammo management with auto-reload
  • TypeScript Compiler upgrades (up to level 5)
  • Ultimate "Refactor" ability (Press R/Shift)
• WebAudio Sound Effects: Synthesised SFX for shooting, hits, explosions, power-ups, heals, Boss appearance, Refactor ultimate, and wave clear — with a mutable toggle in the status bar and Settings panel
• Visual Effects:
  • Particle explosions on enemy destruction
  • Floating damage numbers
  • Hit flash feedback
  • Animated combo meter
• Readable Combat HUD:
  • Compact player HP/max display integrated into the canvas HUD
  • Persistent R Refactor charge bar with percentage readout and a high-contrast ready state
  • Boss health bar with distinct Phase 2 and Phase 3 warning labels
• Frame-Rate Independent Movement: Player, enemies, projectiles, and timers scale with real frame time for consistent gameplay across all machines

🎮 Game Mechanics

Controls

WASD       → Move your player
SPACE      → Shoot TypeScript bullets
SHIFT / R  → Refactor Ultimate (when charged)
ESC / P    → Pause game

On touch devices, the game area shows directional, fire, and refactor controls. Activity-bar buttons open a dismissible mobile sidebar.

Accessibility / Tuning

• Open the Settings sidebar from the gear icon in the activity bar
• Adjust Movement Sensitivity from 0.5x to 2.0x
• Toggle Sound Effects on/off — or click the 🔔 icon in the status bar
• Slider focus is automatically released after dragging so keyboard control returns to gameplay

Objective

Survive increasingly difficult waves of coding errors and deploy your project! Each wave requires you to:

1. Defeat enemies to fill the Release Progress bar
2. Face boss battles when the bar is full
3. Choose an upgrade after defeating the Boss
4. Collect power-ups to enhance your abilities
5. Maintain combos for score multipliers

Enemy Roster

Enemy	Symbol	HP	Points	Behavior
Bug	🪲	10	100	Gradually homes toward the player
Syntax Error	};	20	200	Tanky ranged enemy with aimed shots
Spaghetti Code	goto	15	150	Fast and erratic
Memory Leak	malloc()	40	300	Grows in size and health while slowing down
404 Error	404	15	250	Ricochets and periodically dashes toward the player
Merge Conflict	<<<<	35	350	Splits into smaller enemies on death
Infinite Loop	while(1)	25	400	Spiral movement with four-way projectile bursts
Race Condition	async	20	500	Teleports and attacks from its new position
MONOLITH 👹	LegacyWrapper	600	5000	Three-phase Boss with scaling tracking fire, spread bursts, and minions

Progression System

• Weapon Levels: Compiler Upgrade permanently raises the weapon tier (max 5); Copilot only grants a temporary +1 tier for 8 seconds
• Ammo System: 40 bullets max (expandable), auto-regenerates slowly, reload time 2.5s (reducible)
• Special Meter: The visible R bar charges from regular defeats and switches to a pulsing ready state before unleashing "Refactor"; enemies cleared by the ultimate do not recharge it
• Wave System: Difficulty scales each version release (v1.0, v2.0, v3.0…)
• High Score: Persisted locally via localStorage, displayed on start and game-over screens

Key Components

GameEngine.tsx

Coordinates the game runtime:

• Time-scaled game loop for frame-rate independent gameplay
• Mutable entity state and requestAnimationFrame lifecycle
• Spawn, combat, progression, and upgrade coordination
• Delegates input, collisions, enemy behaviour, and drawing to focused modules
• Wave upgrade trigger → GameState.UPGRADE

game/ modules

• useGameInput.ts owns keyboard listener setup, cleanup, and pause handling
• entityFactory.ts creates enemies, bosses, projectiles, power-ups, and effects
• advanceEntities.ts advances projectiles, particles, and floating text
• canvasViewport.ts keeps Canvas text sharp across display pixel densities
• minimap.ts projects the complete playable area into the reserved telemetry rail
• combat.ts resolves contact, projectile damage, pickups, and entity cleanup
• playerSystem.ts owns movement, status timers, ammo, reload, and shooting
• progression.ts owns defeat rewards, combos, boss completion, and upgrade choices
• refactorUltimate.ts owns activation and damage for the ultimate ability
• upgrades.ts applies selected wave upgrades and permanent run modifiers
• updateEnemy.ts owns enemy movement, special behaviour, and boss phases
• collision.ts provides shared collision primitives
• contentSelection.ts owns weighted random content selection
• renderScene.ts owns Canvas drawing and visual effects

App.tsx

Handles the VS Code interface:

• Activity bar navigation
• Dynamic sidebar views (Explorer, Search, Git, Debug, Extensions, Settings)
• Wave upgrade overlay (three-choice card UI)
• High score persistence via localStorage
• Terminal log display
• Start / game-over screens
• Sound toggle

utils/audio.ts

Lightweight procedural audio:

• No external files — all sounds synthesised with OscillatorNode and white noise
• Global mute toggle
• Functions: sfxShoot, sfxHit, sfxExplosion, sfxPowerUp, sfxHeal, sfxBossAppear, sfxUltimate, sfxPlayerHit, sfxWaveClear

🎨 Customization

Modify Enemy Difficulty

Edit constants.ts:

export const ENEMY_TYPES = [
  {
    type: 'BUG',
    text: '🪲',
    hp: 10,        // Increase for tankier bugs
    score: 100,    // Adjust point values
    speed: 1.5,    // Higher = faster
    color: '#f14c4c',
    width: 24,
    desc: '普通Bug，数量众多'
  },
  // Add your own enemies!
]

Adjust Game Balance

// constants.ts
export const PLAYER_SPEED = 5;             // Movement speed
export const MAX_AMMO = 40;                // Ammo capacity
export const AMMO_REGEN = 0.4;             // Regen per frame
export const SPECIAL_CHARGE_PER_KILL = 5;  // Ultimate charge rate

Add New Upgrades

// constants.ts
export const UPGRADE_OPTIONS = [
  {
    id: 'MY_UPGRADE',
    icon: '🔥'
  }
]

Adding an enemy requires more than its config: extend EnemyType in types.ts, add EN/ZH strings for its descKey, include it in the wave spawn distribution in game/contentSelection.ts, implement any special AI in game/updateEnemy.ts, and finish with npm run verify.

Then complete all four integration points:

1. Add 'MY_UPGRADE' to the UpgradeId union in types.ts.
2. Add upg_MY_UPGRADE_title and upg_MY_UPGRADE_desc to both language maps in utils/i18n.ts.
3. Handle the effect in the applyUpgrade switch inside game/upgrades.ts:

case 'MY_UPGRADE':
  // Your custom logic here
  break;

4. Add a test for the effect and run npm run verify.
