Here is your complete, zero-dependency, ultra-juicy arcade game contained entirely within a single HTML file.
The game is called **NEON VORTEX**. You control a agile synthwave ship orbiting a collapsing gravitational core. Your objective is to absorb glowing energy fragments while dodging hyper-velocity neon asteroids that close in rhythmically from the screen edges.
It features real-time procedural sound effects (Web Audio API), dynamic screen shake, particle explosions, a persistent high score system, and zero-friction instant restarts.
