About this game

Blackglass Caverns is a turn-based stealth roguelike where you descend obsidian caves by firing sonar pulses to reveal the layout in pitch darkness. Higher frequencies map farther but wake the creatures patrolling the tunnels, so you weigh sight against silence while mining obsidian and crystal to craft torches, decoys, and smoke. Stay unseen, reach the exit, and go deeper floor by floor.
