Onyx Dark

Onyx Dark is a flintknapping craft game. Hold near the edge of an obsidian core, drag to aim your antler hammer, and release to strike flakes from the stone.

Strike too close to the edge and the flake crumbles. Strike too deep and the shock cracks the core. Your aim angle sets the flake length, so every blow is a trade between bold removal and fine control.

Shave the core until its silhouette matches the glowing target blade. Later levels demand thinner, more elegant forms with tighter tolerances. Lose core integrity entirely and the stone shatters.

Earn coins for finished blades and spend them in the shop on six real tools: a copper hammer, antler billets, a pressure flaker, a guideline overlay, a resin grip, and the master's eye preview.
