Mosaic lets you visually label what your tiles are — ground, platforms, props — and generates polished platformer & top-down levels automatically. No adjacency rules. No tile terminology.

What makes it different
Mosaic does the tedious parts — edge detection, adjacency, fill, spacing, prop placement — so you stay focused on how your level looks.
Tag tiles by category. Shift-drag captures whole blocks like skies, silhouettes & big props.
Caps, corners, edges and fill are inferred automatically. You never touch an adjacency rule.
Send finished levels to Godot, Unity, Phaser, or Tiled — tilesets, layers and IDs included.
Label a tileset, hit generate, export to your engine. That's it.
