⭐ Complete Stat System Overhaul
- The entire stat engine has been rebuilt from the ground up for accuracy, stability, and long‑term scalability.
- All stats now use a unified map‑based architecture, replacing the old scattered variable system.
- Totals, Bests, Lasts, Time Played, and Run Counts now update through a single clean pipeline at GameOver.
- Stat saving/loading has been fully modernised to prevent drift, duplication, or missing values.
- A one‑time migration system automatically converts old save data into the new format.
- Fixed a long‑standing issue where Best scores were not persisting correctly between sessions.
- Timing logic has been verified for accuracy — run duration and total playtime now match real‑world time precisely.
🎨 Sphere Skin Unlock System Improvements
- Sphere skin unlocks are now fully tied to the new stat engine for consistent behaviour.
- Fixed an issue where newly unlocked skins would not appear in the shop until restarting the game.
- The shop now refreshes unlock states instantly when opened, ensuring skins become available the moment they’re earned.
- Added internal separation between Unlocked Tier and Selected Tier, allowing players to freely choose any previously unlocked skin without it being overwritten.
✨ New Feature: Unlock Notification at Game Over
- When you hit a new score milestone (100, 200, 300, 400, 500…), the Game Over screen now displays a “New Skin Unlocked!” notification.
- Includes a subtle looping flash animation to highlight the moment without overwhelming the UI.
- This creates a more rewarding and satisfying progression moment after strong runs.
- The notification only appears when a new tier is earned — no false triggers.
🛠️ General Polish & Stability
- Cleaned up several legacy Blueprint paths and removed unused variables from the old stat system.
- Improved save reliability after migration to ensure all new values persist correctly.
- Shop UI logic has been streamlined for clarity and future expansion.
- Minor performance improvements during GameOver and SaveGame operations.
