absolutely one of my favorites this year. It's the kind of thing that I would definitely play as a full game. I was really enjoying the mechanics of building an army and controlling them.
One odd thing, I rarely ever used fight mode, it felt too dangerous to put my commander in danger basically. furthermore, I found myself spending most of my time in map mode, telling the critters to kill bots. if this were expanded into a full game, I feel like maybe the player should be rewarded for participating in the battle somehow, otherwise, maybe you could lean into the more defensive aspect, encouraging the hero to continuously produce units while you direct your swarm in the meantime through the map or aerial view. this would remind me of a MOBA in a sense, where your character is essentially your home base, and shouldn't really be participating in battles unless it's an emergency. it might be an interesting dynamic to have the enemies launch counterattacks that you need to defend against if you hold up in one place too long.
Apologies for the extended tangent, but I just think this project has such an interesting concept.
I only had one bug where some units got permanently stuck with an action queue they weren't following, but when I selected them and pressed defend one by one, it snapped them out of it
