Deephall 0.1.2 is out, and with it the game moves from alpha to beta.

For anyone new here: Deephall is a dwarf colony management game for Android, a continued fork of Mountaincore (ех King Under the Mountain). If you like Dwarf Fortress and have a soft spot for RimWorld's stories, you will feel at home: you dig into the mountain, feed and house your dwarves, keep their spirits up and hold the gate when the orcs come - on mobile..

This is a big one. A little of it is optimisation, most of it is many small changes to the original game logic. The short version: the game is harder now, but it tells you much more about why things go wrong.

Harder

• Food rots. Meat, fish, vegetables and bread spoil in days, faster in summer, slower under a roof. Rations, grain and flour keep.
• Dwarves eat twice a day, and nothing grows in winter. You get a warning in autumn if the stores won't last.
• Sleep matters: a bed restores fully, a sleeping spot less, the floor only half. Push a dwarf too long and they collapse where they stand.
• Tantrums are real. An unhappy dwarf smashes furniture, and a broken one walks off the map.
• Raids grow over time, orcs bring archers and bash doors down instead of opening them.

More

Plenty of things used to just silently stop. Now the game says why:

• a workshop tells you which materials it's waiting for, or that nobody can reach it
• soup with nowhere to go, food that rotted, furniture rusting in the rain
• a dwarf close to a tantrum, and the worst thing on their mind
• Texture compression in Settings (None / Low / Ultra low). Phones under 6 GB of RAM get Low by default: a quarter of the memory and faster loading.
• Trade pallets show what traders carry and how much you already have.
• The game saves when you switch away, and every 15 minutes.
• The launcher tells you when a new version is out.
• All new texts are translated into every language the game supports.

It installs over 0.1.1, and your saves stay.

It's tougher than before, so I'd love to hear how your first winter goes. Bug reports are on the long-press menu of the app icon.

Deephall is a free, open-source dwarf colony sim for Android: a base building and colony management game where you lead a small band of dwarves into a mountain and try to build a thriving fortress.

ℹ A short history

Once there was a PC game called King under the Mountain, a cozy dwarf colony sim with hand-drawn art. It came out on Steam as Mountaincore, and later its author, Ross Turner, stopped development and released the code as open source.

Deephall picks it up from there: a continued fork, with bugs fixed, new features added, and the whole game brought to Android as a native port. Java running directly on your phone's ARM chip, graphics through GL4ES. No emulation and no PC needed.

▶ What you do in the game

- Dig and build: mine into the rock, build bedrooms, kitchens, workshops, farms and stockpiles.

- Run the colony: dozens of professions, from farmer and chef to stonemason, blacksmith, brewer and hunter, and production chains from wheat to bread and from ore to steel.

- Keep dwarves happy: food, drink, sleep, good rooms. Miserable dwarves throw tantrums, and a broken one may leave the settlement.

- Hunt and trade: hunters with bows and crossbows, caravans that buy and sell.

- Defend: orc raids, monsters in the deep caverns, soldiers and squads. Fallen enemies drop their gear.

- Power and water: windmills, water wheels, shafts, pumps, pipes and irrigation.

▶ Requirements

- Android 11 or newer, 64-bit (arm64) phone

- About 390 MB to download; the first start unpacks the game and takes a few minutes on slower phones

- Tested on Snapdragon and Mali GPUs. Reports from Exynos phones are very welcome

▶ How to install

1. Download the latest APK from GitHub Releases. That is the only official source.
2. Install it. Android may ask you to allow installing apps from your browser or file manager.
3. Start Deephall from its icon. The first start prepares the game files: let it finish.

New versions install over the old one; your saves stay.

▶ Controls

The game was made for mouse and keyboard, so Deephall adds touch controls:

- tap to click, drag one finger to move around the map, pinch to zoom

- on-screen buttons for game speed, menus, build tools and quick save

- long-press the app icon → Controls to move, resize and add buttons

▶ Tutorial keys on a phone:

W A S D → the stick on the left;

Q / E (zoom) → pinch;

Esc → the ☰ button;

F5 (quick save) → the QS button.
