POLYGON FRUIT MERGE PUZZLE

Introduction

"Polygon Fruit Merge Puzzle" is a physics-based falling puzzle game that runs directly in your phone. Powered by the Matter.js physics engine, it offers realistic yet comical object interactions. The player's goal is to merge fruits efficiently within a limited space to achieve the highest possible score.

Gameplay Mechanics

1. Evolution Cycle
Fruits range from Level 0 to Level 11. Each merge evolves the fruit into a larger shape. The evolution generally follows a cycle of "Circle -> Polygon -> Circle...", increasing in size and point value.

Lv0: Circle (Pink)

Lv1: Triangle (Salmon)

Lv2: Square (Peach)

Lv3: Pentagon (Lime)

...and so on, repeating with different colors and larger sizes.

2. Probability System
In addition to normal fruits, "Super Fruits" with special effects are selected based on the following probabilities:

Transformation Type (1.0% each): Dark Super Circle, Golden Super Triangle

Designed for "Board Refresh" and "Chain Reaction." When unrelated fruits pile up, transforming them all into the same shape triggers massive, simultaneous merges.

Environmental Type (0.1% each): Blue Super Square, Red Super Pentagon

These are rare "Happening" elements that dramatically alter the game flow.

3. Environmental Gimmicks: Water & Fire

Water: Triggered by the Blue Super Square.

Buoyancy: Simulates buoyancy based on the fruit's size. Objects submerged in water will float, changing the dynamics of the stack.

Drag: Movement and rotation are dampened underwater.

Fire (Explosion): Triggered by the Red Super Pentagon.

Effect: Clears all fruits on the screen, granting a score bonus.

Interaction: If water is present, the fire effect "fizzles" out and fails. To clear the water, you must use a Transformation Type item (Dark Circle or Golden Triangle), which evaporates the water upon impact.
