## 🌟 Game Mechanics & Features

- **One-Touch Vector Thrust Physics**:
  - Hold down to fire dual plasma thrusters with upward acceleration.
  - Release to enter gravity dive with terminal velocity clamps.
  - Smooth dynamic tilt angles match flight trajectory and velocity.
- **Dynamic Laser Matrix**:
  - **Static Laser Barriers**: Floor or ceiling suspended high-energy beams.
  - **Oscillating Laser Gates**: Sine-wave sweeping vertical beams.
  - **Spinning Di-pole Hubs**: $360^\circ$ rotating laser barriers.
  - **Intermittent Zappers**: Timed charging and lethal pulse phases.
  - **Homing Missile Drones**: Flashing warning reticles and supersonic tracking drones.
- **Close-Call Near-Miss Protocol**:
  - Skimming within inches of active lasers or missiles triggers a **"CLOSE CALL!"** bonus (+500 points) with Doppler swoosh SFX!
- **Data Shards & Combo System**:
  - Collect floating gold data diamonds in arcs, sine waves, and rings.
  - Consecutive collections build combo multipliers up to **x5** for massive score surges.
- **Cyber Upgrades & Power-Ups**:
  - 🛡️ **Cyber Shield**: Absorbs a fatal laser or missile impact, triggers a screen-wide EMP wave, and grants temporary invulnerability.
  - 🧲 **Data Magnet**: Lasts 10 seconds. Emits cyan magnetic lightning arcs that draw all data coins into your thrusters.
  - ⚡ **Hyper Warp Overdrive**: Supersonic rampage! Smashes all lasers and drones into glowing showers of sparks.
  - ⏱️ **Chronos Matrix**: Dilates time by 50%, allowing precision flight through tight laser corridors.
- **Procedural Audio Synthesizer**:
  - Continuous dual-layer jet engine thruster rumble (filtered white noise + sub-bass saw wave) that reacts dynamically to thrust inputs.
  - 130 BPM 4-on-the-floor synthwave music with driving kick, snappy snare, rolling bassline, and arpeggios.
  - Responsive retro SFX for near misses, coins, shields, warnings, and sonic booms.
  - 100% generated on-the-fly via Web Audio API (zero audio files needed).
- **Persistent High Scores**:
  - Automatically saves all-time high score, best distance, and total coins in browser `localStorage`.
