Build a very simple version of Bloons Tower Defence game.

- Prim base class with health, pathfinding, and damage system

- RedSquare, YellowCircle, BlueHexagon with unique stats

- Tower base class with targeting, fire rate, and drag-and-drop placement

- SingleShotTower, AOETower (with flash effect), TripleShotTower (spread)

- TowerManager with drag and drop and placement restrictions

- Projectile with trigger-based collision

- GameManager with lives, win/lose conditions, singleton pattern

- DrawPath with automatic EdgeCollider2D generation

I've covered all four OOP pillars - inheritance, encapsulation, abstraction, and polymorphism - plus coroutines, physics, UI, and design patterns like singleton.

Please review my game and let me know what you think.
