/**************************** GAME DESCRIPTION *********************************/
/******************************************************************************/
/* 
**Game Title**: **Sand Tower**
**Description**: Build towering sandcastles, perfect your alignment, and climb to the top! Sand Tower awaits! 🏖️🏰
**Objective**:
	- Players aim to construct the tallest sandcastle tower.
	- Perfect alignment of sand blocks is crucial for stability and bonus points.
**Visuals**:
	- The game features a sandy beach backdrop.
	- A basic sandcastle stands in the center, serving as the base.
	- The central tower is the focal point.
**Gameplay Mechanics**:
	- **Beach Bucket Mechanism**:
		- Players use an upside-down beach bucket.
		- When the player taps, the bucket tips over, releasing sand.
	- **Sand Block Placement**:
		- Sand falls vertically from the bucket onto the base.
		- The player must time their taps to stack the sand blocks.
		- Perfect alignment grants bonus points.
	- **Lives System**:
		- The player starts with 3 lives (represented by small bucket icons).
		- Each time a sand block isn't centered enough and falls, 1 life is lost.
	- **Scoring**:
		- Points increase with tower height.
		- Bonus points for precise alignment.
	- **Game Over**:
		- The game ends if the player loses all their lives (buckets).
**Audio**:
	- Gentle beach sounds (waves, distant chatter).
	- Encouraging music during gameplay.
