I didn't initially realize that weapon info and other unit info were stored in separate folders, which is why I thought damage couldn't be changed. I did try editing a bunch of values to see the result, and the game play quickly became ridiculous. Speed values, for example, that sounded about right in my head led to absurd speed in game. So it seems that re-balancing well would take a lot more thought, planning, and trial-and-error than I initially thought, lol. Especially with how many units there are. Not sure if I'm actually up to the task.
It was satisfying giving bazooka ants absurd range, though, and giving the cannon beetle rapid-fire bombardment. So absurd changes are easier than actual fair changes.
The new features and changes you added sound really cool. I will try to check it out soon.
