Enhance game generation prompt with professional polish requirements

VISUAL POLISH ADDITIONS:
- Gradient backgrounds (no solid colors) via CSS or canvas
- Particle effects on player actions (jumps, attacks, pickups)
- Screen shake on impacts (camera offset for 200ms)
- Web Audio API beeps for all actions:
* Player actions: short high beep
* Pickups: ascending tone
* Damage: descending tone
* Victory: cheerful melody

GAME STATES REFINEMENT:
- Title screen: "Click to Start" prompt (clickable anywhere)
- Game over screen: Final score + "Play Again" button
- Brief instructions on title screen

These requirements ensure every generated game has:
- Professional juice and feel
- Immediate audio/visual feedback
- Polished presentation matching commercial indie games

Generated games will now be significantly more engaging and polished!
