I love the art and the idea of enemies also being your power source. Just two quick notes, though. First is that this game could really use a destroy action; there was a lot of times where I accidentally placed a build the wrong way or I wasn't using one anymore but I couldn't get rid of it. And second, I got stuck on one of the rounds about halfway through because I placed a gust that was pushing a cage breaker away, which never died. I would love to see this idea expanded further!
