 ☘️ A cross platform tool to visulize and analyze texture (usually used for console game font) by tiles.  It is inspired by `Crystal Tile 2`, and more flexible with custom lua script (for more complex situation, such as swizzle) and command line support.  Also, it supports for droping file, save decoded image and show cursor moving in tiles.
