The coal doesn't seem like it is timed right with the other components. As the others say that it makes something every 10 ticks and the coal buyer seems to buy faster then the others. Even though the iron foundry and buyer are running at 100%!
Could you make it so you could right click with the mouse icon and it would sell the component that you clicked on. Just like in your other game reactor idle? Also Shift right click to remove all of the same thing would be great too.
Hello, max will eat as many full levels as possible, so if you only have enough to eat 1 full level then it will just do the one.
