This is a pixel art factory building game where you extract ore refine it into ingots and sell them for money.
Start by placing miners that automatically produce ore then connect them with conveyor belts and direct the flow toward smelters.
After refining send the ingots to exporters to earn cash and expand your production. Select a tool from the bottom toolbar click on the grid cells to place machines and use rotation to change their direction.
Press R or the rotate button to cycle the orientation before placing and clicking an existing machine of the same type also rotates it.
The demolish tool lets you remove objects with a partial refund.
Watch your cash and earning rate in the top panel and experiment with routes to build an efficient production line.
