• Export Options:
  • JSON export for game integration with structured data
  • PNG export with transparent backgrounds (key 0)
• Responsive Design: Works on various screen sizes

Perfect For:

• Game Developers: Create sprites, level designs, and UI elements with direct JSON export
• Pixel Artists: Intuitive grid-based drawing with symmetry tools
• Indie Creators: Quick prototyping and concept art creation
• Educators: Teaching pixel art fundamentals and structured data concepts

Use Cases:

• Platformer level design (assign keys to walls, enemies, collectibles)
• Top-down maps (grass, water, forest, mountain tiles)
• UI wireframes (buttons, text fields, navigation elements)
• Animation frames (export JSON and implement color cycling effects)
• Dynamic palette swapping (change visuals by switching color schemes)

The structured JSON output makes it easy to integrate your creations directly into game engines. Every block is mapped to a key rather than a specific color, enabling powerful palette swapping capabilities.
