I love this game, but arcs seem a bit op. you can just spam them and then wreck every bot that comes your way.
a power settup like this makes it even more powerfull
Also, this is basicly the difinitive way to feed factory blocks
According to my calculations, you are producing 22 coal/s but only consuming 12.67 coal/s. You only need 7 Coal Centrifuges. 5 Spore Press should be able to produce up to 90 oil/s, but even 11 Centrifuge can only consume up to 60 oil/s. 2 Spore Press can produce 36 oil/s, which is enough for about 6.5 Centrifuge. Still, that's a pretty impressive setup.
