I am actually surprised this game did not get more attention, this is an amazing twist on the survivors genre. It was amazing to spawn many little guys to do my bidding. The formations added a good amount of depth.
You did ask for serious feedback, so I will suggest improvements/ things I noticed.
- The UI does not scale well with fullscreen.
- The bosses should have health bars and basic animations for their attacks.
- Enemies should show some kind of feedback (flash/knockback) when damaged
