Reworked music, sounds, added ghost piece and fixed some bugs

🎵 Sound & Music Overhaul I’ve completely reworked the game’s audio experience! The music has been remastered for better quality and flow, and I’ve added new sound effects to make the gameplay more satisfying. Every piece movement, rotation, and line clear now has its own distinct sound.

👻 Ghost Piece Feature A new visual aid has been added to help players plan their moves better - the ghost piece! This transparent preview shows exactly where your current piece will land, making it easier to plan your strategy and achieve those perfect placements.

🐛 Bug Fixes Several gameplay issues have been addressed to make the experience smoother:

• Fixed piece rotation behavior in certain edge cases
• Improved collision detection
• Resolved some visual glitches
• Enhanced overall game stability

Try out the new version and let me know what you think! Your feedback helps make the game better with each update.
