🌐 Internationalization & Audio Update!

Got some fresh updates for you! 

• Multi-Language Support: The game now supports English and German! The language is automatically set based on your operating system—if your system language isn’t supported, it defaults to English.
• Immersive Background Music: Added in-game music that blends into the action and keeps the energy up! Let me know if it enhances the experience or needs tweaks.
• Menu & Game Music Volume Control: You can now adjust the volume of both menu music and gameplay music—for simplicity, they share the same slider!

Jump in, test it out, and let me know how it feels! If anything seems off or could be improved, I’d love your feedback.
