Pelaaja, the purpose of upgrading is to reduce the energy strain. Upgrading miners is usually necessary for efficiency, cause you would need an extra power station for every few extra miners. And you have to account for the overall load it puts on the energy system, e.g. when there's a big wave of ships and you need power for defense.
Tip for Circunus 16. Start at the top middle of the screen and very slowly move down to the beat. Then when the lasers finally reach you at the bottom, speed back up to the top and repeat. While you are moving down, you should have enough to get to a couple overcharges. Before I couldn't even manage to finish without losing 5 hearts, but with this method I beat it with only 2 lost.
it's necessary for the plot.
