Dig! Demon Castle

The heroes are coming to kidnap your Demon King — so grab your pickaxe and DIG! Dig! Demon Castle is a reverse tower-defense roguelite where the dungeon itself is your weapon. Carve tunnels, grow a monster ecosystem, and crush the invading heroes. HOW IT WORKS - Dig tunnels to release nutrients from the soil - Nutrients spawn Puni (slimes). Puni eat and evolve into Lizards. Lizards hunt Puni and evolve into Dragons - A real food chain: feed it, balance it, and it will fight for you - When the heroes invade, your ecosystem defends the Demon King FEATURES - Two modes: endless score attack & a 15-stage Expedition to topple the Human Castle - 11 monsters to discover, including rare ones born only under special conditions - Golden Puni, ghostly Borei, and a runaway Princess worth a hefty ransom - Permanent upgrades: train each monster's HP, attack, and speed, plus 18 unique Traits that deepen what each monster does best - Retro pixel art, chiptune sounds, and classic RPG-style windows - Quick runs: one game takes just a few minutes - Premium game: pay once, no ads, no in-app purchases Every hero you defeat becomes nutrients for your dungeon. Nothing is wasted. Protect the Demon King. The shovel is mightier than the sword.
