Wow, there's a lot of game here. I like the idea of combining a colony builder with vampire survivors combat in between rounds, and the gameplay is fun.
I got about 10-12 rounds into it before losing. When you don't get enough food, I think there should be one round of starving before you die and lose the game (if you don't manage to get enough food on the next round, you lose completely). Equivalently, you could have one round's minimum amount of food storage capacity.
I had a hard time figuring out the mechanics at first. I unlocked a new ammo type but didn't realize I needed to build the armory to equip it (maybe ammo should be researched in the armory). I was also sometimes confused about how conquerAnts disappear between rounds. I assigned one a bed and then sent it to battle, but it never returned (I think? Might be wrong about this).
The stats are a bit hard to read and contextualize since all the scales are different. A bar chart showing where each stat is on the distribution might help.
For the combat, I'd probably zoom out just a little bit (maybe 10-15%) and make the background pan at the same rate as the enemies when walking. Sometimes, I misjudge how quickly I'm moving and run right into an enemy who has just fired a wall of ants, killing me instantly (although my ants are just too weak).
