Particul Calm mining that grows while you plan

It starts with a click. Tap the screen and particles break loose, fall, and stack into a growing heap of pixel sand at the bottom. Sell what you mine and your balance climbs; the more you mine, the more particle types you unlock, each rarer than the last. Early on it is just you and the mouse, and there is something quietly satisfying about watching the heap change colour as new materials show up. Nothing punishes you for pausing or playing slowly, so it works as a background companion: mine a bit, sell a bit, glance at the pile, get back to whatever else you were doing.

Clicking forever is optional. Buy extractors to mine for you; they start slow, but upgrades make them faster and more powerful. In the lab, spend resources on a research tree that unlocks new tech, and hire traders to do the selling while you choose which items they handle. The marketplace lets you swap abundant resources for the ones you actually need, and negotiating can improve the exchange rate. When luck is against you, gamble: a wheel and a slot machine improve sell prices and the odds of finding rare particles. Every system feeds the others, and deciding where the next upgrade goes is most of the game.
