Coin Harvest

Coins pour from a pipe and pile up on your plateau. Robotic arms swing through the heap, sweeping them off the edge and into your collection. That's the loop. Now make it bigger. Unlock up to 6 islands, each with its own arm. Upgrade speed, magnetism, critical hits, and sweep range. Push your flow rate higher. Watch bronze coins give way to silver, gold, platinum, diamond, emerald, and ruby, each worth more than the last. Four realms stand between you and the top. Each one has its own islands, its own upgrades, and its own prestige track. Ascend when you are ready. Shift dimensions when you have conquered enough. The numbers only go up. The whole thing runs as a small transparent widget on your desktop. It sits on top of everything, stays out of the way, and keeps earning while you do whatever else you want to do.
