Loving the trial, definitely will purchase! 50 points already!
Couple things I've noticed, maybe if you could expand the search radius when defending the void knight (because he gets ranged and my guy will just watch him get hit, even if whatever is hitting him is within camera view).
Also the script seems to only prioritize spinners if they are there before the shield drops on the portal (if one spawns while youre attacking the portal your character keeps attacking the portal rather than prioritizing the spinner).
Hope any of this helps!
