ChatGPT vs Claude: Lumina Drift — a single-file arcade game

Create a complete, polished, single-file web game called "Lumina Drift" using only HTML, CSS and vanilla JavaScript (no external libraries).

Game Concept:
- The player controls a glowing light particle called "Lumina".
- The game is an endless side-scroller with continuous gravity.
- Instead of classic flapping, the player uses a "Pulse" mechanic: every click / tap / spacebar creates a short energy ring around Lumina that pushes it upward smoothly.
- The pulse has a short cooldown and a satisfying visual + slight screen shake effect.

Visual Style (very important):
- Dark, modern, minimalist aesthetic.
- Background: deep space with subtle parallax stars and soft nebula gradients.
- Lumina: a soft glowing cyan-magenta orb with a beautiful particle trail that follows its movement.
- Obstacles: geometric portals and energy bars in neon cyan and magenta. They should feel clean and futuristic, not pixel-art.
- Smooth animations, particle effects, and a clean neon UI.

Core Gameplay:
- Start screen with title "Lumina Drift", short instruction, and a "Tap to Start" button.
- Gravity constantly pulls Lumina down.
- Pulse gives upward velocity (smooth, not too floaty).
- Obstacles scroll from right to left with increasing speed over time.
- Collision detection must be precise but fair.
- Score increases with distance + combo multiplier when the player pulses in rhythm.
- High score saved in localStorage.
- Game over screen with final score, high score, and "Play Again" button.
- Progressive difficulty: obstacles get closer and move faster the longer you survive.

Technical Requirements:
- Everything in a single HTML file (embedded CSS + JS).
- Use HTML5 Canvas for the game rendering.
- Fully responsive (works perfectly on both mobile and desktop).
- Touch controls + mouse + keyboard (spacebar).
- 60fps smooth performance.
- No external assets or CDNs — pure code only.
- Clean, well-commented code.
- Add subtle screen shake on pulse and on collision.
- Particle system for Lumina’s trail and for pulse rings.

Extra Polish:
- Soft glow effects using canvas shadows or multiple layers.
- Smooth camera follow on Lumina (slight lag for modern feel).
- When the player dies, Lumina explodes into particles.
- Combo text that appears when the player gets consecutive good pulses.

Make the game feel modern, fluid, and addictive — better and more original than classic Flappy Bird. Focus heavily on visual polish and satisfying feedback.
