Really good game! I love the road mechanics because it gives off strong Factorio and Mindustry vibes. The dynamic music that changes as pollution rises is also a super nice touch!
However, I'd love to see a clear main goal, as the timer alone doesn't really provide that sense of purpose. Maybe adding objectives like "Build 5 coal factories while keeping pollution under 80%"? Also, a minor note: when clicking the forest icon, the balance UI briefly flickers with raw fractional values.
Anyway, thanks for the game, I really enjoyed playing it! Good luck!
