I really like the idea. Growing and trying to keep a battle going for as long as you can is a fun and unique concept.
I do agree with the other comments that it is quite confusing to play. It isn't clear what the totems do given the lack of visual feedback. It's also quite buggy. I don't know if it's intended, but it seems like the totem areas are blocking the movement of soldiers. I think you forgot to make them trigger colliders.
I do believe the concept has potential, and with some improvements could make for a really fun game.
