UMBRA

Carve the light

A shadow-matching voxel puzzle. You're shown the three shadows a shape casts, not the shape itself — carve the stone that made them, then chase the fewest blocks possible for a perfect three-star solve.

Why Umbra

Pure spatial reasoning

No timers, no combat — just the shape and the shadows it must cast.

Optimal solves, not just solves

Any correct shape passes a level. The fewest blocks wins all three stars.

Progress that follows you
