I've created "Gravity Garden" - a puzzle game about growing plants in varying gravity conditions. Here's what I've implemented:

**Core Features:**
- **Gravity Manipulation**: 5-directional control (up, down, left, right, zero-g) affecting plant growth
- **Plant Growth Mechanics**: 5 unique plant types with different growth rates, resource needs, and gravity resistance
- **Resource Management**: Water, light, nutrients, and energy systems that affect plant growth
- **Environmental Challenges**: Zero-gravity zones, seasonal cycles affecting growth conditions

**Gameplay Mechanics:**
- Click/tap to place plants (costs resources)
- Plants grow dynamically following gravity direction
- Each plant type generates specific resources when mature
- Seasonal cycles (Spring/Summer/Autumn/Winter) modify growth rates
- Level progression based on growing mature plants
- Plant hybridization system to create new plant varieties

**Plant Types:**
1. Sunflower - Generates light
2. Vine Plant - Generates water, flexible growth
3. Root Tree - Generates nutrients, gravity resistant
4. Crystal Flower - Generates energy, rare
5. Spore Bush - Generates nutrients with unique growth

**Special Features:**
- **Zero-Gravity Zones**: Floating areas where plants grow freely
- **Hybridization**: Combine 2 mature plants to create unique hybrids
- **Branches & Leaves**: Plants develop complexity as they grow
- **Seasonal Effects**: Each season modifies resource generation and growth rates
- **Progressive Difficulty**: More objectives and zones as you level up

**Sound Effects:**
- Plant growth sounds
- Gravity shift effects
- Harvest collection sounds
- Hybrid creation tones
- Ambient space garden atmosphere

**Mobile Support:**
- Touch controls for plant placement
- Responsive panels for smaller screens
- Optimized UI for portrait and landscape modes
