⛏ UNDERGROUND — dig deep, light your way, survive the dark

A tiny Terraria-style sandbox where light is a resource and the deeper you go, the richer — and deadlier — it gets. The whole game fits in ~46 KB: no downloads, no loading screens, just click and dig.

Light does not pass through blocks. That one rule shapes everything: caves are pitch black until you bring fire, your torch supply decides how deep you dare to go, and the sun itself is a weapon — zombies and skeletons that survive until dawn burn alive in the sunlight.

🌍 A living layered world

• 700×500 tiles of real geology: grass → soil → clay and limestone strata → stone → a molten lava ocean that forms the floor of the world
• Wandering cave systems, coal near the surface, iron in the mid-depths, gold only far below
• Two active volcanoes that periodically erupt — slow liquid lava flows downhill and cools into fresh stone
• Day/night cycle: peaceful slimes by day, the undead rise at night

🔥 Craft, smelt, grow

• Tools and swords in four tiers: wood → stone → iron → gold (+ a bone sword from skeleton trophies)
• A clay furnace with real fuel burn-times: wood 15s, slime gel 30s, charcoal 45s, coal 60s. Smelt ore into bars, char wood into charcoal, cook zombie flesh into actual food
• Plant acorns — trees grow through visible stages (sunlight required, 3 minutes to full height)
• Drag-and-drop inventory, hotbar, tooltips — everything mouse-first

🌀 Find the secret rooms

Three hidden brick chambers are buried somewhere in the stone. Inside each — a portal to HELL: one shared underworld of hellstone, eternal darkness and gold twice as rich. The portal takes its toll: 50% of your HP, every crossing.

Controls: WASD + Space — move/jump, S — fast fall, LMB — dig/fight/place, E — inventory, 1–0 — hotbar, Esc — pause. Language: Русский / English (switch in the menu).
