A cross-platform incremental crafting & smelting idle game
You inherit a crumbling furnace and a pile of raw stone. From that humble start, you'll mine ore, discover alloys, queue smelting jobs, and slowly build a fully automated forge-town — until your first Ember Crystal ignites and everything resets… stronger than before.
The Loop
Start by clicking stone and coal. Buy your first pickaxe. Smelt iron. Unlock bronze, then steel, then mythril. Automate production with mines, workshops, and furnaces. Research upgrades to speed everything up. Eventually condense Ember Crystals, ascend, and begin again with permanent bonuses.
mine → smelt → craft → automate → ascend → repeat

Prestige Loop
Ascend, gain Essence, unlock permanent bonuses
Prestige & Eternal Upgrades
Ascend after creating Ember Crystals to gain Essence. Spend it on permanent upgrades that carry across every run:
• Eternal Miner — start each run with a free Pickaxe
• Ember Memory — keep 10% of coins on ascend
• Forge Mastery — permanent smelting speed bonus
• Ancient Veins — permanent ore production boost
• Twin Furnaces — start with a free Auto-Furnace
Unspent Essence also boosts production, mining, gathering, and smelting every run.
Technical
