How to play: Hover over a category button to open the dropdown, then click a building to select it.
Hover over buildings on the map to see what they do. During DAY, collectors generate energy, mines generate minerals.
At NIGHT, cannons and mines need battery power (within 3 tiles). Moonlit Arrow fires for free.
Click a mine then select Upgrade to level it up — +50% output per level, cost doubles.
