Thanks, the idea is that the damage is joined together with the missing health, I was looking for a more non-physical connection between the elements or being control related.
I'm aware that the waves of enemies could be better, maybe having more delay between the spawn of an enemy and the next one or the turrets shoot only when on screen, but it was part of the idea trying to figure out where they were and kill them from a safe distance.
Thanks for the feedback!
