LiteChat Race Result

Certainly! I'll create a colorful, comfy 2D scroll shooter with a 3D effect using Three.js. It will feature:

- A scrolling background for a sense of movement
- A player ship with multiple guns
- Enemies that spawn and get tougher over time
- Random bonus drops (faster fire, bounce bullets, extra guns, extra life)
- Live updates and a playful, vibrant style

I'll implement this in a `runjs` block with clear DOM setup, colorful visuals, and game logic.

Let's do it!

```runjs
// Clear previous content
litechat.target.replaceChildren();

// Create a container for the game
const container = document.createElement('div');
container.className = 'p-4 bg-gradient-to-br from-purple-100 via-pink-200 to-yellow-100 rounded-lg shadow-lg max-w-3xl mx-auto';

// Add a title
const title = document.createElement('h2');
title.textContent = 'Colorful Scroll Shooter!';
title.className = 'text-2xl font-bold text-center mb-4 text-purple-700';
container.appendChild(title);

// Create canvas for Three.js
const canvas = document.createElement('canvas');
canvas.width = 800;
canvas.height = 600;
canvas.className = 'border-4 border-purple-300 rounded-lg shadow-inner';
container.appendChild(canvas);

// Create score and info display
const infoDiv = document.createElement('div');
infoDiv.className = 'mt-3 flex justify-between text-purple-800 font-semibold';
const scoreSpan = document.createElement('span');
scoreSpan.textContent = 'Score: 0';
const livesSpan = document.createElement('span');
livesSpan.textContent = 'Lives: 3';
infoDiv.appendChild(scoreSpan);
infoDiv.appendChild(livesSpan);
container.appendChild(infoDiv);

// Append container to target
litechat.target.appendChild(container);

// Game state variables
let gameRunning = true;
let score = 0;
let lives = 3;

// Bullet bonus effects
let bonusEffects = {
    fireRateBoost: 0, // in seconds, decreases over time

### Summary:
- Creates a vibrant, comfy scroll shooter with 3D effects.
- Player can move left/right with arrow keys or A/D, shoot with space/enter.
- Enemies spawn at the top, get faster and stronger.
- Random bonuses drop, offering faster fire, bounce bullets, more guns, or extra lives.
- Colorful background with a grid pattern for depth.
- Smooth, animated, and fun!
