Wow, this is a brilliant concept and a well-executed game! Not only are the vibes immaculate (art style and audio are excellent and fit the narrative theme nicely) but the gameplay loop is really cool. I definitely found in challenging to react to my towers getting lost, but the power unlock of more surface area and "budget" is really cool. I had two thoughts to make it even better: (1) I wonder if the time between consumption of your towers and next enemy spawns could be increased, so I could prep my defenses - like a break between rounds (maybe), and (2) I wonder if you could consume towers based on their proximity to the center, so that I could control which of my defenses "stayed alive" between rounds more easily (that may already be happening, not sure). Overall, nicely done!
