This is a super cool game, something about ants and automation has always been super cool to me but I've never seen a game pull it off well enough - while this is definitely a small game, it has definitely managed to hold my attention!
I really enjoy the central elevator unlock, but it seems like the ants refuse to use it more often than not, and it also sucks that the miners don't seem too interested in digging around it to use either, even with the contractor upgrades. I've found it's better to dig tunnels manually and have only hauler ants, than to let diggers to their job - if that's intentional, then great! If not, would there be a way to at least update the ant pathing to prefer using the elevator when possible? And possibly have the digger ants try to dig around the central elevator?
Otherwise, I'm very much enjoying it!
