Hello and welcome to the Game! This is an Idle factory game. The Gameplay can seem pretty complicated so I will try to beak it down simply.
Over here we have all the buildings that you can build. Each one has a money cost and a power cost. click on the building to select it
Next click over here on the board to place the building. If you have power, the building will produce resources. I would recommend placing 1 windmill and 3 iron mines to get started.
Also Click a building again in the build area to sell the building for 100% refund.
Hit the sell goods button to sell everything for more money. Thats it! Have Fun!
