Geode Cavern

Geode Cavern is a cozy crystal-hunting mini game set deep in a candlelit mine.

Pick a geode from the cavern row and read its hints: weight, texture, and faint shimmers whisper what hides inside. Press and hold to charge your hammer, then release inside the golden zone. Strike too softly and the rock wastes your hammer. Strike too hard and the crystal cluster inside shatters, ruining its value.

Every geode hides a surprise: precious Amethyst, warm Citrine, banded Agate, or a hollow dud. Your hammers are limited, so every swing matters. Score equals crystal value times integrity, so keep those clusters whole.

Spend your coins in the Miner's Shop on six real upgrades: a Gilded Hammer that widens the perfect zone, a Shock Pad that softens overcharged hits, a Crystal Stethoscope that reveals what beats inside, Spare Hammers for longer runs, a Miner's Lantern for sharper hints, and a Lucky Chisel that lures rare geodes.

Features:
- Charge-and-release hammer strikes with a moving power bar
- Four crystal types with value and integrity scoring
- Six shop upgrades that truly change every run
- Twelve runtime-synthesized sound effects, no audio files
- Themed dialogs for pause, results, revive and purchases
- Progress, coins and gear saved automatically

Grab your hammer. The cavern is glittering.
