Umbral | HTML5 3D Dual Shadow Puzzle Game

Umbral is a striking 3D puzzle built around light, form and perspective. Every level drops a sculpture onto a pedestal lit from two directions, casting a shadow on Wall A and Wall B at the same time. Rotate the piece with a drag and watch both shadows shift together. The goal is to align both silhouettes with their targets at once, not just one.

The journey runs through 50 handcrafted sculptures across 5 acts, from simple classical monoliths rotated on a single axis to full dual-axis pieces that demand real spatial reasoning. Every sculpture comes with a short real art-history fact, tying the puzzle to the Classical, Renaissance, Mannerist, Constructivist and Surrealist eras it is themed around. A Pure Vision seal rewards players who solve a level without using a hint.
