Nice game. I really liked the look of the UI and the twist that you need to manage the ammo and not directly the towers. Sometimes the UI was a bit cumbersome. I think it would be good if you could select the turret to unload and load it by clicking on the turret in the base. Also assigning the workers is a bit cumbersome, maybe assigning them directly by drag and drop. At the moment you need to first unassign them from a task and then reassign to another task. The possibility to directly assign them to another task would be very helpful.
Still a very solid entry and congratulations to this!
