Crystal Shapes Game

A fun puzzle game where you navigate a crystal around the screen and collect matching shapes!

Game Features

• Dynamic Shape Morphing: Press SPACE to change your crystal between circle, square, and triangle forms
• Shape Collection: Collide with shapes that match your current form to collect them
• Orbital Attachment: Collected shapes orbit around your crystal in a beautiful pattern
• Bounce Mechanics: Non-matching shapes will bounce you away
• Smooth Movement: Use arrow keys for fluid crystal navigation

Prerequisites

1. Install Crystal language (https://crystal-lang.org/install/)
2. Install Raylib library for your system:
   • macOS: brew install raylib
   • Ubuntu/Debian: sudo apt-get install libraylib-dev
   • Arch Linux: sudo pacman -S raylib

Installation

1. Clone this repository
2. Install dependencies:

   shards install
   

Building and Running

# Build the game
crystal build src/crystal_shapes.cr -o crystal-shapes

# Run the game
./crystal-shapes

Or run directly without building:

crystal run src/crystal_shapes.cr

How to Play

• Arrow Keys: Move your crystal around
• SPACE: Change your crystal's shape
• Goal: Collect shapes that match your current form
• Avoid: Shapes that don't match (they'll bounce you away)

Game Mechanics

• Your crystal starts as a golden circle
• Shapes spawn randomly around the game area
• Matching shapes attach to your crystal and orbit around it
• Non-matching shapes act as obstacles
• The more shapes you collect, the larger your orbital system becomes!

Key Features

1. Player Control: Use arrow keys to navigate your crystal smoothly across the screen
2. Shape Morphing: Press SPACE to transform between circle, square, and triangle forms
3. Collection System: Matching shapes automatically attach when you collide with them
4. Orbital Mechanics: Collected shapes orbit around your crystal in mesmerizing patterns
5. Bounce Physics: Non-matching shapes create a bounce effect, adding challenge to navigation
6. Visual Effects: Golden crystal with special glow effects and colored shapes with attachment indicators

Game Design

The game creates a physics-based puzzle experience where:

• You must strategically change your shape to match targets
• Collected shapes create an increasingly complex orbital system
• The challenge grows as your orbital system expands
• Quick reflexes and planning are rewarded
