PileBird

PileBird is a collection of mini-games with multiple gameplay modes. There are three different game modes. Players need to complete each level in sequence, collect stars and fragments, unlock subsequent levels, and ultimately clear all levels.

### Game Mode 1: Stacking Blocks

Core Gameplay: Drag blocks from the lower preview area to the upper platform and stack them precisely on the designated positions.

How to Play:
- Tap a block in the lower preview area
- Drag the block to the target platform above
- Release your finger; the block will fall due to gravity
- Place blocks precisely on target positions without overlapping on top of other blocks

Timer & Star Rating:
- Each level starts with a countdown progress bar
- The bar decreases over time; the faster you place blocks, the higher the star rating
- Star rating:
- 3 Stars: Very fast placement
- 2 Stars: Fast placement
- 1 Star: Average placement speed
- 0 Stars: Time over — fail

Level Structure:
- Each level contains static blocks (fixed base) and dynamic blocks (to be dragged and placed)
- After all dynamic blocks are placed, the countdown begins
- When the countdown ends, the level is cleared

Failure Conditions:
- A block falls off screen to the bottom
- The countdown reaches zero

### Game Mode 2: Jump Tower

Core Gameplay: Control the character to jump upward continuously on moving wooden platforms. Reach the target floor count to clear the level.

How to Play:
- Tap the screen; the character jumps upward
- Land on a moving wooden platform to stand and prepare for the next jump
- Landing exactly at the center of a platform earns a "Perfect Combo"
- Consecutive combos at 3 and 5 times trigger notifications
- At 7 consecutive combos, the character flies into the sky, collects many coins, and clears the level directly

Platform Mechanics:
- Platforms enter randomly from the left or right side of the screen, moving toward the center
- Platform movement speed varies randomly
- Each platform stops at the center for the character to stand on

Clear Condition:
- Reach the target floor count (shown at the start of the level)

Failure Conditions:
- Hitting the side of a platform (not the top) causes the character to be knocked away
- The character falls off the screen

Special Obstacles:
- Fireball: Instant failure upon contact
- Iceball: Freezes the character for 1 second

### Game Mode 3: Draw & Fold

Core Gameplay: Press and hold to draw a straight line; release to make the line fold along the target shape's outline. Covering the shape clears the level.

How to Play:
- Press and hold anywhere on the screen to start drawing
- The line extends from the starting point continuously
- Release to make the drawn line fold along the shape's outline
- The line folds from one vertex to the next, gradually conforming to the shape

Star Rating:
- Star rating is based on the drawn line's length relative to the shape's total perimeter
- Get 3 stars (Perfect) when the line length closely matches the perimeter
- Lines that are too long or too short affect the rating
- Meeting or exceeding the target star count clears the level

Clear Condition:
- The folded line achieves a star count equal to or greater than the target star (targetStar)

Failure Condition:
- The folded line's star count is below the target star
