Control a miner, mine and place blocks to distance yourself from the lava pits. As you mine, you'll uncover gems - choose wisely from those that appear in the mined areas and set up your defenses. When selecting a gem, the surrounding tiles lower into water, allowing air units and projectiles to pass through. Find the safest spot on the map, position your miner, and start the wave! Your gems will unleash attacks on enemies as they attempt to drag your miner into the lava. Once the wave is cleared, your miner gains experience, increasing the chance of finding higher level gems. It's time to mine again! Merge gems and select powerful augments every few waves to unlock the full potential of your defenses. Each map introduces unique twists to the core gameplay - some feature waypoints that enemies must pass through before going after your miner, while others introduce entirely new mechanics that shake up your strategy. Survive long enough, and you'll face a powerful boss. And if you can defeat the boss, get ready for an epic grand finale showdown!
