Interesting concept, felt like a tower defense game without the defense, or a super minimalist version of a city / colony builder with a survival element to it. It seems that if you right-click a construction area, it's destroyed, and then you're unable to build anything else on that spot. Is it supposed to work like this and I'm missing something or could it be a bug? Solid entry with a lot of potential, I hope you keep working on the game.
