That's the main thing I want to improve in future rounds. Right now it is just place, wait, move, repeat. I'd like to make placing your turret more intentional and useful.
I did have that idea as well, but I didn't really have time to implement it this round though. It was little different to it though. Throughout the level you would collect resources and fight a few enemies (like what I had here), and then each level would end with a 'horde attack', where many more enemies would come and you would have to tactically place turrets and traps across 3-5ish waves.
