Neat concept, some pretty cool implications and potential areas to expand upon in the future! Was fun to manage and plan out an attack (it was also nice to be on the attacking Side of a tower defense for a change lol) . Things got pretty crazy in the end which is always fun. My biggest bit of feedback would be that it's a bit difficult to get around/ know what's going on everywhere so maybe in the future you could either make the move speed a bit bigger, or make the map a little smaller / make the camera see more of it, so you can really get a sense of what you're managing.
Cool stuff good work!
