Underloam

You wake on the surface of a procedurally generated world with nothing — not even a pickaxe. Punch a tree. Make planks. Make a workbench. By nightfall you'd better have walls, because the night does not care about your plans.

⛏ A world that goes deep

• Four surface biomes — forest, desert, jungle, and ice — each with its own terrain, trees, and dangers, stretched over a world of 1.2 million tiles
• Caves carved by ancient worms, lit by your torches, flooded by real flowing water and glowing lava that obey their own physics
• A buried underworld of ash and fire at the bottom of everything
• Ruins of those who dug before you — abandoned rooms with loot chests holding accessories you can't craft: double-jump bottles, swift boots, regeneration bands

⚔ A power ladder with teeth

Wood, stone, copper, iron, silver, gold — every tier unlocks ore you could see but couldn't touch. Three summonable bosses guard the path, each with honest, readable attack patterns: the Cave Tyrant below the stone, the Hive Mind in the jungle, and the Molten Warden in the underworld. Fight them with swords, bows, or magic — your build, your call.

And when the Warden falls? The world itself changes. New ores surge through tunnels you've already explored. The night grows things that walk through walls. Everything you knew gets a second act.

🏠 A home worth defending

• Build houses and NPCs move in — a Guide with advice, a Merchant with wares, a Nurse with bandages, a Sorcerer with secrets
• Farm crops, cook up healing berries, keep a torch lit
• Wire your base: levers, pressure plates, lamps, gates, and pumps — build a zombie airlock or flood a moat with lava
• Weather rolls in, blood moons test your walls, and meteors fall from the sky carrying metal that shouldn't exist

🌱 Made the old way

• Plays offline, in any browser — the entire game is a single file, no installs, no accounts
• Deterministic worlds: share a seed with a friend and explore the exact same world
• Autosaves constantly; death only costs the coins in your pocket (go get them back)
• Full keyboard rebinding, gamepad support, local achievements
• Every recipe discoverable in-game — no wiki required

The wall between you and the next tier is always visible before it's passable. That glint of silver two sessions before you can mine it? That's the whole game, winking at you.
