A physics sandbox where you want the ragdoll to suffer. Launch a skeleton down a gauntlet of spikes, hammers, saws, flame walls, and bounce pads every bone that cracks pays out bone fragments, and every broken bone flings the ragdoll into the next trap for a ricocheting combo chain. Reinvest your earnings in the shop between runs: more traps, higher tiers, deeper arenas, weirder physics.
