🔮 New System: Seal Stones
The time-based progression system has been completely replaced with the Seal Stone system
5 Seal Stones spawn sequentially across the stage — find and destroy them to progress
Each Seal Stone destroyed lifts the darkness, making the world brighter
A Mini-Boss spawns at the location of each destroyed Seal Stone
Destroy all 5 Seal Stones to trigger the Final Boss
💀 Boss Rework: Bullet Hell
All 22 bosses completely reworked with ranged barrage attack patterns
Melee attacks removed — bosses now use bullet hell-style projectile patterns
New barrage types: Aimed shots, Fan spreads, 360° Radial bursts, Lasers, Markers, Walls, Spirals
3-Phase boss structure: P1 (100~60%) → P2 (60~30%) → P3 (30~0%)
P3: Boss activates a shield and summons 2 elite guardians — defeat them to break the shield
Difficulty scales automatically by stage position, chapter, and phase
📷 Camera Zoom
Camera zooms out during boss battles for better visibility
Zoom level increases with each phase (P1 → P2 → P3)
Camera returns to normal after boss defeat

Seal Stone destruction and Mini-Boss kills reward gold based on progression
