## Description

You are the keeper of a cursed pickaxe and the dungeon beneath a quiet village. Adventurers keep coming for your treasure. Let them.

Dig. Hold and drag through the earth to carve tunnels. Chain blocks into combos, find gold veins, soul crystals and sealed secret chambers, and push into a Digging Frenzy.

Build and trap. Every tunnel you dig is a path the heroes will walk. Line it with spikes, sticky slime, arrow walls, hungry mimics and rolling boulders, and watch the combos stack up.

Harvest. Fallen heroes leave souls behind. Sweep your pickaxe through them to chain them together: the longer the chain, the bigger the multiplier, up to a Soul Surge.

Awaken. Every soul feeds the colossal dragon chained in the lava below. Its eye opens, its chains strain, and when you're ready it tears free, walks out through your keep and drags you to a harder region. Spend Dark Hearts on permanent upgrades and dig again.

Features
- A whole pixel-art dungeon on one screen, from the village road to the lava
- 5 traps and 3 servants: skeleton diggers, goblin repairers and soul-saving ghosts
- 4 hero classes plus champions, each with their own tricks
- Soul chains, trap combos, Digging Frenzy and Soul Surge
- 10 permanent upgrades across endless, escalating regions
- 16 achievements
- Original synthesized soundtrack with a dynamic raid layer

Controls
- Left mouse: dig, chain souls, place traps and servants
- Right mouse: mark cells for skeletons, cancel placement
