Pretty fun, a decent demo overall, it's basically a part of Mindustry game as an auto-battler.
No saves, short, only way to quickly restart is page reload.
Seems like 3-cost power pole with big range is forbidden to be rolled on first round, as it's all you ever need for the whole game. This and geothermal are probably the only ones you can't roll round 1.
If you use resource-fed power source, it starts at low speed, e.g. only 10/XXX for your whole base. Miner should not work as a power connection node.
Power source -> Pole -> B1 -> Pole -> B2 - here B1 should be on 2 different isolated power networks at the same time. You can set up a 100% powered miner, if you don't let any other poles touch the miner as a workaround.
