Redefine the
FM experience

Patch USS for styling and UXML for layouts, then ship fonts, icons, and images in the same pipeline. Build complete FM skins without rummaging through folders.

Style with USS/CSS

Use USS or CSS to tune colors, typography, and styles, then patch UXML to reshape layouts. Simple and Advanced modes available.

Edit Layouts

Create custom tile layouts by re-arranging their position, size, and adding stacked tiles.

Custom Icons & Backgrounds

Replace sprites, textures, and backgrounds with your own imagery. PNG and SVG support is built-in.

Preview, Build, Apply

Preview changes, build your bundle, then apply the skin directly to your game.
